Kinda reviving this, but since Lisk wrote in there he identified one possible cause, I decided to make a new thread. Also since I've got games to drop in a solo custom game, this might make it easier to figure out the issue. Spoiler: Some notes from reports All games seem to have Hades in play Games usually drop late game, like 18+ (so maybe due to some summon/send interaction?) Some seem to drop when imps don't get ported? Can't be, since games also drop at the start of waves (e.g. 14) Lisk 08/08/2018 yeah that looks like a different, much more rarer one. I will probably fix that once we switch servers to another provider that would give us more visibility into remote crash logs I don't have a 100% repro on this yet, but it happened in most customs I tried today, but never consistently. I had no drops with Gateguard, Harbinger, LoD. Only with Hades. The last clip in the video is particularly funny, since I tried harbingers and swapped one for Hades later on with the game instantly dropping on wave start. Since there's no obvious pattern whatsoever, I assume it's something weird, but definitely seems to be related to the way Hades works. Some weird summon behavior (only summoner with 2x insta summon), some timer issues not getting handled properly, something to do with porting units after clearing come to mind. Note: All games were started in a freshly launched client, no prior games or anything. - Video: - Logs: I've included the logs used in the clips, as well as some earlier attempts which are more spammy builds though.
