Well, I've been testing for a couple of days now, and I have seen no further evidence of the bug. *Knock on wood*. The ONLY change I made from when it was happening every few minutes was to remove Sky UI 2.2. I use NMM, I use a bashed patch after change and currently I have 255 active plug ins with 40 more merged into the bash and ghosted. 450 active mods total in NMM I don't know why this change worked for me but it did. I was using Sky UI 2.2 just fine until I installed the dll loader by Shadowman. That's when I started having the problems. I did not uninstall that mod however as I wanted to continue using the plug in. I decided I can live without Sky UI 2.2 if everything remains playable. So it still seems like a combination of the dll loader and Sky UI to me, but that's still hypothetical. Certainly seems engine related as obviously neither of those even includes a plug in.
