If you change the collision group of a part that is not inside workspace (E.g. in ServerScriptService) by changing it in the properties panel using the collision group name, the underlying collision group ID will not be changed automatically, causing studio to show this warning, which cannot be resolved by following the instructions.
The moment this part enters workspace, the ID is updated automatically and the warning is gone.
Expected behavior
Updating the collision group outside of workspace should always update the collision group ID so the properties panel does not show confusing and unresolvable warnings. Iām unsure if these being desynced could cause issues without the part being in workspace.
