Seriously? You think that a crash is just gonna be ignored, purely on the basis that it occurs (seemingly only) when people exit the game? Whether or not it actually really adversely affects the experience or not, its still a bug.
The crash is a lot worse for full screen users. It blocks out the ability to use the 'esc' buttons and forces you toopen the task manager via "ctrl+alt+delete".
I got the crash after recetly attempting to use the deco tool on a bomb bunker. When clicking off the deco tool, some of the colouring disappeared, so I rage quit instead of going through the effort again. For whatever reason, after pressing "esc", the game crashed with that "memory read/write" error. Just a white haze over the game and unable to use the 'esc' key again.
