Sorry mods, I didn't know where to put this - it's not an graphical bug, but I guess it's still a bug.
The "anthill" scenario is bugged in pak64 - I set up a coal route to get some cash flow, but then get informed that I've won after one month with about 25,000 passengers transported! ;D
I'm on 112.3 if that helps.
This is a program bug, which is already fixed in the nightlies.
