Dear Devs
I could never report this in-game as when it happened I was always kicked out (but could reload and continue playing with no problem), but I thought I should let you know:
This test I had a number of crashes where i got the message plug-in failure on a completely white background in the window. This seemed to be happening frequently in the area around some new building projects (streets Tower West maybe Tower North etc.) - and often when changing streets there maybe. I don't remember this happening a lot the previous test weekend which was my first, but then I was a total beginner and didn't really go to the project areas.
Didn't interfere with gameplay a whole lot as I am keen and just reloaded ;-) but I thought you'd want to know.
Playing on a macbook, OS X 10.6.6, Safari 5.0.3, latest mac version of Flash (well the latest one 9 days ago which I had to specially download as Glitch would run with the older version I had installed :-p)
