yes it takes a long time and also takes its toll on your disk and your CPU... Mine got one core's activity maxed out during the whole process, for the disk strain thoughn, it was an SSD so it was forgiving on me. Basically i just played some XCom EW while the whole damn thing sluggishly updated itself.

But that was only after cleaning all my browser's cookis, and "fixing" my GOG account with the refresh/reset link i once was given by the support for account related issues that i finally saw the patch; though not as a GOG Downloader item either...

Btw, talking about shutdown targets... did they fix the bug where a shutdown mech could practicllally get away with murder if it was also knocked down after being shutdown, getting itself spared from the powering back up phase and just having to stand back up and then guard/move and/or shoot ? Well i suppose having harder time knowning things down now with the stability change may adress this "in a strange way"

HI Sorry for the late response but this forum site software (I am forced to admit is pretty bad) https://www.gog.com/downloader/listing/battletech_game is the only place I have ever found to download patches. I wold kiss anyone on the lips if they'd provide a better link, especially if they were a girl. But still that's all I have. Wish I could help more but this company we purchased our game from doesn't seem to want to make much obvious about how to handle updates or new information. Good luck friend. Please let me know if you learn anything I'm unaware of. I will always repost any useful info wherever I can. Thank you. Also to user Djaron or anyone who cares, yeah I'm still on day 3 of 5 of my full RE INSTALL download. I wish I could tell you more about my results but I can't because I don't even know if this install will work.
I seriously seriously recommend that anyone in the future looking at a game that needs large updates, please just use any platform that natively handles large updates, I generally like Valve's Steam system, but GOG just seems to have failed up and down on this one. I don't know how much of that is GOG's fault but they seem to be completely silent about the issue. At least as far As I can say. I try to be fair because as a businessman myself I know how hard it can be to satisfy everyone. But this game is so niche and easy to satisfy on a consumer level that I can't understand how awful ly handled I feel things have been. I hope things work out for the best and I hope GOG can fix things.

IDK if here's the place to point out the prblem but I can't even properly reply or edit my messages here because the buttons do not properly load under firefox or msft edge, haven't tired chrome.

May I make a suggestion to GOG general support and forums people? Ever notice how simple forums JUST WORK? Forums should let people post messages to each other in a threaded or nonthreaded context. Your forum seems to be designed (I hope not intentionally) to hinder this type of communication at every turn. Please make your forums less flashy and more usable. All this streamlined forums stuff isn't helping anyone communicate with each other or with you. And we want to help YOU. Trust US.

well, for once, from what i could hear and read in various places, it seems GOG itself is not at fault this time.

Some developper are packing up their updates in a strange way, and often in a non incremential/universal way (hello titan quest anniversary edition)...

GOG already provides Galaxy to the devs so that they can push updates in a faster way (but i dislike galaxy afaic, plus the whole concept of downloading unpacked full files instead of applying a patch to modify content of an asset file, especially a bit monolithic multi GBsized one, is very annoying and non optimakl plus very punishing for people with bad connections)
I remember the battletech 1.02 patch (that was needed to apply the 1.02-to-1.03 that was never released as a standalone) was barely a couple of hundreds of megabytes worth of updated content, but through Galaxy it would requires me todownload 5gb of unpacked raw files

So, to get back on topic, the supplying (or lack of it) of either incremential or universal patches as standalone compressed installers is mostly the responsability of devs, what takes some time though, on GOG's side, is the whol checking and validating such patches (when they are even supplied) because (and now this one IS on GOG at least) of a clear lack of unallocated human ressources for the manual checking and validation of such things, which can delay some updates from coming here.

anyway, still, for a 16gb sized installer of a game, and for people who have bad connection (me included), i am afrid to admit the whole Battletech first two monthes of life after release were poorly handled by the whole chain (but mostly the devs), and i can relate and feel sorry for OP very genuinely. And the game is still in a disastrous technical state regardless of recent patch. I really hope they will dare to NOT let it in such state before ever trying to sell us more content DLC and expansions during the game's lifespan cycle. Because while the game as its core is great, it is overshadowed by the execution of it, sadly I really wish it would be better on this matter ! I dont think it is ever fixable except from rewriting the whole thing for scratch, bur hey, devs, you are welcome to proove me wrong, very gladly indeed...

Edit: and yes, OP, this forum software is rather poor, frankly. It was already underpowered back in 2008 while some phpbb and other kind of forum/boards solutions were very widespread... I dont know if it is supposed to be part of the charm or whatever, but yes, the forum engine is not very convenient
