Loobinex: That's no surprise. Anybody who uses the final nightly build will have that problem. Instead, use
KeeperFX Unofficial 0.4.6, it's a build with all new fixes/functionality of the nightly builds, but the ones that don't work taken out. Download
here.
I've been trying this Unofficial v0.4.6 and have had numerous problems.
Now it's been quite a while since I've played KeeperFX, a few years I think, though I do remember finishing it, while I'm not sure I can finish this Unofficial KeeperFX.
Here's some of the problems I've been having, keeping in mind I don't know if they're limited to the Unofficial or are also present in the normal KeeperFX since it's been so long, I do however not remember having any crashing/graphics problems.
Can't choose to pick up high or low level monsters from the monster panel. (this alone is a serious problem)
Imps often fortify instead of mine gems and sometimes completely ignore gems, keeping in mind fortifying is what they should do when having no other job. (I had to lock them up with the gems at one point)
Can't slap an imp to stop it carrying a body or something.
(Imps all round are a pain, more than usual)
Shift doesn't speed up scrolling, and other minor things I can't remember..
By the time I got to Mirthshire things were going pretty crazy. Mousing over the map would show hundreds upon hundreds of units that aren't there (possibly thousands).
https://i.imgbox.com/QlE3Ssuq.jpg I've noticed the map isn't very good/accurate in this regard, showing things that don't exist and not showing things that do but on Mirthshire it was impossible to remain unnoticed just how bad it can be. Perhaps it had been happening all along, I do know it continued onto the next level as I then kept my eye open for it.
Kept playing Mirthshire and eventually part of the lower screen would flicker black (like blocks vanishing) but managed to finish the level. However the next level, Blaise End, started freezing (not responding) the game.
I was going to say that I'm close to giving up on it, though I just tried two more times while making this post and Blaise End has frozen the game both times after varying amounts of time. Basically I've now given up.
I can't remember what version of KeeperFX I played last time I finished it, I also don't know if one of the later KeeperFX builds work better than this. Though as it stands now it's unfortunately completely blown the wind out of my sails.
