Ok, crashed again on wave 31 while doing the exact same thing. Didn't get a chance to screenshot it as the crash dialogue box closed immediately due to my inputs :( I tried for a third run to replicate the conditions, but unfortunately (also fortunately?) I was unable to do so and instead ended up completing the map without a hitch: Sorry guys! I did 7.5 hours of WW crash testing though :P Glad to be free of it. https://steamcommunity.com/id/Voodootissue/
https://steamcommunity.com/id/Voodootissue/ Finished WM without issue, but crashed on wave 31 of WW: I was repositioning one of the summoners using the 1235 keys and at the same time I was using flash heal (/ button next to numlock) on another summoner. I'll be attempting WW tomorrow and will try to replicate the issue, and if not, I'll hopefully end up completing it instead!
