Lot of crashes in custom games

Hello!
I am encountering a lot of crashes in custom games.
Just played a few matches (2 players vs IA) and I got 3 crashes - most of them after a click on the minimap, but not always. The other player got only 1 crash in another match.
It already happened previously, but this evening was especially bad…

We sent the report, but I also have question/suggestion about this: if we are in two players in the current custom game and 1 of us crash, why aren’t we able to invite the other player back after he restart the game? This could really help in this case.
I don’t understand why there isn’t a way to do this.
