started for me when I was playing with the new physics.. I was close to done with a new physics layer in The Kirsten's veiwer. Once I saved it, I could no longer attach or edit it. I soon found out that was true of everything in my inventory.
If it's a LL glitch I'm sure there will be a fix along soon (I hope). The cache thing is a bigger concern to me. If it won't reset, I'll be maxed out soon and will just crash every 3 seconds no matter what.
On the good side, I'm at least stuck in a state that isn't hard on the eyes. Problem is, my SL work requires me to change clothing pretty frequently so it's not an option to stay like this forever
