just encountered this issue (switch and android versions both), have quite a few add ons running but its never been an issue til now. they all run fine on worlds, but the second i boot it up on realms, it removes one pack in particular and always that singular pack. none of the others are affected nor run bad, the world has no issues and no notable difference from adding new packs to a pre establish world, and its worked for the 7 or so other packs. there is a message every time its attempted stating "some of the selected content could not be applied."
i initially thought it might be an issue with the pack but if that were the case it should not work with worlds either
pack that isn't working is the recently made "Golem Pets Add-On" by DeepwellBridge
