Not sure if this is a 1.11 bug or my computer's fault (it's a bit dodgy at the moment due to a failed and not yet fixed Norton deinstallation), but it has never happened to me before.
I had just loaded my 2nd 1.11 game fresh from desktop and took my strafer out for a hell pit run. I entered /player 8, cast the valk and proceeded to the waypoint. Just that I couldn't activate the waypoint! It just came up a flash of that waypoint window and went away again. The same happened with the Options screen, so i couldn't exit either.
I changed back to /p1 and the waypoint worked just fine. Changed to /p8 again and everything was fine as well.
No idea if this is related to 1.11, but thought I'd post it just in case.
