--- Comment #12 from Adam Bolte abolte@systemsaviour.com --- I was unable to get multiplayer loading at all, even with staging rc2. I attempted to load it maybe 5 times. Clicking the multiplayer button from the main menu results in the game attempting to restart, which always crashes for me.
Once the game crashes during loading, it always seems to crash during loading until I exit Steam and run `wineserver -k` before trying again.
The game also seems to fail to shutdown cleanly a lot of the time (maybe 2 times out of 3), and the DOOM exe process has to be killed off manually.
