Roblox Animation editor unable to move parts

[PlaceRebuilder]

Quite frequently while animating guns I get this issue.
I see an animatable part but it doesnt move when I drag in the arrows. Doesnt rotate either.

It’s just stuck.

The handle is anchored, the lever is not.
Nothing is welded to the lever either, its completely free to move.
The model is not connected with the ground.
Works just the same with humanoid instead of controller.

I’m just completely unable to move anything.

Was this part able to move and then became stuck or was it always stuck? Can you provide the gun model or place file so we can try to reproduce this?

I might have found the issue.
One of the parts had welded sides, this created a weld without it being a “visible weld” and that’s why it didn’t move.

Ohwell, case closed.
