Details:
While trying to crash the game, I used a plain map from the editor which I
resized to 1x1, the map looked like this:
Gg, Gg, Gg
Gg, Gg, Gg
Gg, Gg, Gg
and loaded tried to start a multiplayer match on it.
There was some UB

and the game appeared to have locked up.
The UI was updating but it didn't react to any clicks.
When I ctrl+c'ed it in the terminal, a heap use after free showed up (see
logs).
