I know Crate just wanna give us the best, but a hotfix should come faster to fix what the update broke, like the new legendary ring not dropping for lvl85 chars, and not to add more changes that will break some more stuff to wait for another hotfix (another update together that breaks something) to fix.
As Zantai said, there are some big behind-the-scene changes happening with the fix, including some things with the engine itself.
Assuming this, It can certainly be said, that such an exhausting amount of work takes time. I personally hope for permanent fix to constant crashes.
So, be patient and wait.
Actually, I’ll just redirect you here, since Medierra commented on this - http://www.grimdawn.com/forums/showthread.php?t=51837&page=3
Because it’s turned into a full blown patch, with extra grubbins on top.
Also due to the changes the testers are having the risk of complete loss of chars/stash etc…and I’m sure the OP would much rather wait until this is fixed before releasing this to the public.
