Sorry. Since the update steam just put me through this morning, none of the errors are showing up anymore, with the exception of one that comes when I open a context menu before an action has completed on a stack. In the case of the two I remember, each was just a small red rectangle popping up in the lower right corner with the word "Error" and a number on it. One was when I opened the game, and one was when I loaded my save. None of them appear to have a noticeable effect on gameplay. Does Zomboid keep logfiles somewhere that I could attach? Do you still want to know if they stopped after the last update?
