[0.11.17] [cube] Multiplayer segfault
Re: [0.11.17] [cube] Multiplayer segfault
The stack traces in 0.11.17 are broken, so we can't do anything with this. On the other hand some MP related (and also not MP related) crashes were fixed for 0.11.18, so I will close my eyes, hope for the best and move this to resolved. If you have any further problems, please bump this thread or open a new one.
