Attention, Beta! No Final! Release Notes:

Fixed rare crash when industry upgrades (during campaign missions)
Fixed rare crash when selecting vehicles tab in line window
Fixed rare crash when removing stops from a line
Fixed keyboard scrolling in "Buy vehicles" dialog
Fixed construction parameter list not scrollable
Fixed medal "Large crowds" in USA mission 04

Heh, "rare".

This latest update was basically what I was waiting for to start actually playing the game, but going through the tutorial, I ran into this crash twice in a row before I realized what actually triggered it. Still haven't seen what that tab looks like, since it crashes 100% of the time for me, when there's at least one vehicle in it.

But good to know that it's been fixed already. :) Hoping that patch will get to gog soon!
