I just got this error when I wanted to close the SK:

Assert

File: c:\_skyrim\code\tesv\bssystem\BSTSmartPointer.h

Line: 429
Bad Refcount

Abort - Retry - Ignore


What to do?

I'd like to know too, I seem the get this error message when putting trees and plants in my worldspace.

Whenever I get errors I just click ignore and all seems to work out. Only about 5% of errors actually mean bad things for your mods.

Though, leongt, if you're getting it when placing plants and it prevents you from contuing that may be bad...

Try reinstalling the CK.

Strange thing with my bad refcount error it only happens if I try to put more that 3 plants or trees in at a time, It's so frustrating having to put 3 in then exit out of the CK then open it up again and put 3 more in

Yeah, reinstall. That shouldn't be happening. I'm making a worldspace with thousands of plants added in and nothing like that's ever happened.

Happened to me too, when I made trees spawn harvestable ingredients. Tested ingame, worked fine. Will see how it works out in the long run.

Did a reinstall of the CK but I'm still getting the same error so I just clicked ignore and my mod still loads up and I can continue my work without any problems
