No, I also mentioned this on the alpha forum. I haven't used the caches (yet). Tested editing yesterday on a small scale and that worked fine, but on my museum project I lost a tree I edited to a certain location and I can't figure out why that happened. And still happens, as I dragged an instance to another location, stopped editing, saved file, and hit render. It started repopulating (which wasn't necessary, but that's another issue), and it popped back to the old location.
