Crash to Desktop on Single Player Custom Map

Game crashed to desktop mid-game. I haven't had any problems before this other than the "too many converted minions" lag issues. I did notice that the gold shrine near the middle of the map that I had claimed and was working had turned into a blank black square not too long before the crash occurred, and had clicked on it a time or two to test it. The gold vortexes I had placed on the shrine were plainly visible, however. Lag was present but manageable at the time of the crash. Crash report is attached. 2017-02-14_122942.zip
