CollisionGroup and CollisionGroupId don't match error

[Jermartynojm]

I’m trying to change collision group of a mesh part inside a limb of an NPC. The problem is that when I do it, the CollisionGroup property changes but the CollisionGroupId (deprecated) doesn’t. It comes up with this error I’ve never seen:

Can’t seem to find any info about the error online (apart from this forum post: CollisionGroupId not changing on UpperTorso nor LowerTorso). Even when I modify an accessory’s (a hat on the NPC) collision group, it comes up with that error - so it doesn’t matter if it’s a limb or not.

How can I fix the error? Should I just ignore it? Is the CollisionGroup changing successfully?

Edit: this is happening to every part in that Model. Even if it’s not a limb of the Humanoid.

This error is breaking my game, too. Hopefully someone finds a solution to this.

This is also causing havoc in my game. It seems to exclusively affect meshparts.

Given by this CollisionGroup error - #3 by Iamafop it seems to be just a roblox bug/quirk.
