Lost full perms on my prims.

I was linking prims together and accidently linked to a prim someone else made that was no transfer. When I unlinked the set, all of my prims were no longer transfer and all the permission buttons were grayed out. Is there anyway to fix this? And why did it happen like that?

Assuming you didn't run into a bug...

Is there a chance the prim you linked with was actually a linkset (more than one prim) and there's still a 'no transfer' prim in the linkset? To see if that's the case (and assuming the prim wasn't made by you) use the 'Inspect' (Right-click, More, More again, Inspect) tool to check the creator of all the prims. If you spot one you didn't create, click on the row and it'll highlight the prim with purple outlines.

Other possibilities would be: you deeded/undeeded to group or gave/sold it to someone (or someone with mod permissions on you took it) and they gave it back (which would cause the next owner permissions to take effect).

If there's a no transfer/no copy/no modify item in any (or multiple) of the prims' inventory that could cause the permissions to be grayed out as well since the permission-restricted items will determine the permission for the entire linkset.

Last resort, if an annoying one: unlink the entire set, and prim by prim check each prim's permissions (and its inventory) before linking the whole bunch back together.

Good luck .

(Edited to add that if you build by copy-dragging new prims instead of rezzing them, make sure that the prim you used was full permission in the first place, and the same thing if you use a building tool that rezzes prims in which case there could be a 'no transfer' script inside of the prims as well)

Nothing I did worked. I think the sim is bugged. I put in a support ticket to have the sim checked out. Thanks for the tips though.
