The game crashes when I join a local server set up by my brother. We both bought the game from steam and it was working fine until now. His client doesn't crash, but my other friends who are trying to join the server keep crashing.

Thanks for the dump! Can you also send rwr_game.log from %appdata%\Running with rifles from the crashing PC?

Here you go sir!

Hm, can't spot anything off in the log. The dump didn't seem to make too much sense in the debugger, for some reason.

There must be something wrong with the debug symbols I stored for 1.22 so I'm going to have to rebuild it and re-release it in Steam. Would be great if you guys could try it again with it, I'll let you know when it's out.

Alright, the build has been updated. Allow Steam to update the game and retry joining the server when you can, and re-send the crashdump for me to take a look at. Thanks!
