I had sometimes strange bugs in multiplayer:
-sometimes the game is broken and the units does not make anything (I had a few games with this problem)
-I had a game vs dante. I started but the timer was at 0:10 and the creeps spawn later instead of 1:00 but I was not able to cap the bases -> it was really strange maybe you see it in the video:
-I always have crashes with dual Xeon E5 2670 in ashes otherwise the system seems to be totally stable -> If I made troubleshooting in steam I get a corrupt file but after fixing the file the game crashed again
