I've heard of a few new crashes - if you can post your output_log.txt in the forum, along with machine specs and GPU driver versions, I'll see if I can work something out. I'm afraid that it looks like Unity's instanced support for AMD drivers is a little... er... shoddy. Not my fault!
I'm off to eat lunch now, but I'll be back in the saddle tomorrow!
If anyone works out a fix for the random crashing, please please let me know!
