Hello Strands,
The crash you're experiencing is a very old recurring issue that's still
on our list. I personally can't reproduce it. At one point I could and I fixed the cause for some players, but other players continued to get this problem.
The possibility that the season could be part of the cause is something I will look into this week. It's not an easy one to solve since it's a core DirectX rendering issue and could be dependent and influenced by many local factors (other programs running, graphics drivers, etc.). Some players get this and others like myself can alt-tab repeatedly without a problem.
I would like some further information to help try to track this down yet again.
1) Can you give me an exact location where you are crashing?
2) Does it seem to be location based for you, or does it not matter? (For example, does it happen in a forest area or looking at the lake just as easily as it does in the middle of a large tribe area?)
3) Do you crash every time you alt-tab or is it random? If random, how often? (1 out of two times? 1 out of 10?)
I would really love to finally put this one to rest.
Thanks!
