Reproduction Steps
If you first add a CollectionService tag to an instance on the client, then add any other tag to that instance on the server, the original locally added tag will be removed on the client.
I’ve attach a repro file:
CollectionService repro.rbxl (37.0 KB)
Expected Behavior
I would expect that my locally added tags would continue to exist, as well as having server tags.
Basically, I would expect that local tags and server tags would merge, rather than overwrite
Actual Behavior
When I add any server tag, all of my tags that were added from a local script are removed
