I'd like to nominate Shadow Warrior 2.
It seems that the end of the Christmas event (and accompanying update 1.1.8) has broken the trainer, which now crashes the game. It was working fine a few days ago, not so anymore. All functions that are implemented as console commands will get the error message "xxxx is readonly":
Link. The money and skill point option do not work.
On Jan 12th, the devs released an update that stated winter is over, and the in-game HQ also changed accordingly. Either that or the trainer does not work after a certain mission. As the trainer actually causes reliablly reproductable crashes, (press F1 before loading the game, at menu -> crash at load. If the trainer is activated anywhere after load, the game crashes at shutdown, or may crash while attempting to loading a new level.) I'd say the former. Save game here:
LinkThe mission in question was at ~69% completion,
Spoiler:when you go to get the oyabun.
But as I explained it is most likely not the mission but the update that caused the incompatibility.
