If I'm searching the store with Slitherine Ltd. and Polish language filter, it shows that all Panzer Corps 2 editions have Polish but according to their store pages they do not have one.

Ouch, these ratings...

I guess it isn't too much of a loss that it does not have a Linux version.

Old habits die hard...went reflexively to where the GOGDownloader button would be, but nope. So this wasn't the most convenient to download via the browser, but not the most inconvenient one either. Please keep maintaining offline installers (meaning downloadable without any Galaxy use at all) for this game and other new releases.

Somehow the game works... then once in a while it does NOT launch and crashes on launching. I am not sure if it is because I am using GOG as the launcher or if I am able to launch offline. It seems strange that sometimes I am able to launch and play, and other times not. Any suggestions? (and if one of them is to download the offline version how do I know if I did?) This is really confusing!
By the way, even when it DID work I kept getting the error message: "Error: invalid Config File. Please reinstall your game or contact support". Normally I hit okay, ignore it and hit play and am still able to play the game. Whats going on?
