After map editor crashed, game starts up very slow, sometimes not at all

I was in the editor using the random map generator and was playing around with different settings. My game would crash if i had the wrong combo of map type or theme, and when I went to load back up, it took FOREVER, sometimes now it wont load at all. After multiple restarts and verifying game cache in steam at best it takes way longer than it did before, at worst it wont start at all, and sometimes the game is very unstable.

Anyone had this happen to them? Any idea how to fix?
