Very interesting--working with the 8/27/2017 1727 & 1734 UFO builds--*not* TftD--(both builds) Nightly I have a similar problem, I think--it occurs right after the beginning of the 2nd month, right around the first UFO encounter--as soon as I hit Intercept and then choose the vehicle, the game throws me back out to the desktop--with an error message that says something like:
[30-08-2017_22-36-30] [FATAL] A fatal error has occurred: Interface geoCraftScreens not found
[30-08-2017_22-37-27] [FATAL] OpenXcom has crashed: Interface geoCraftScreens not found
...or something to that effect--no such file exists in any of the folders from what I could see. I repeated this after reinstalling the game from scratch--crashes at the same time, after that save is loaded.
Before this I had used the 8/01/2017 0005 Nightly to save the game--so I reinstalled the 08/01 Nightly--and everything is *fine*--the crash no longer occurs after loading the same save!
I'm wondering if it could be some kind of savegame incompatibility between the 08/01 build and the 08/27 build? What do you think?
Running on Win10x64, build 16278, AMD RX-480 8GB @ 2560x1440, Crimson 17.8.2s--simply put, 08/01/17 is rock solid--I can't *make it* crash...
In fact, the crash I relate here is the only one I've had with the nightlies. Great job, btw.
I am going to install 08/01/17 0005 again and report back here as to whether the game still crashes.
Edit: Ok, reloaded same save back into 08/01/17 0005 and no problems at all--played for an hour past where both of the 08/27/17 were crashing--with the same error as I relate above. Thought you might like to know.
