Running 1.12.2, Baubles version 1.5.2

On full reloads of Minecraft or when switching dimensions back to the standard overworld, any baubles that don't need to be activated will stop working until they're taken off, the inventory closed and re-opened and the bauble replaced.

This isn't normally too big a deal, except some baubles allow you to stand on water without turning it into ice or swim undamaged in lava. Or for another example, in Terraqueous there are cloud blocks that aren't solid unless you're wearing a specific bauble or have creative flight. This can be a bigger problem if you make a cloud house and log out in there - and then log back in, and fall right though the cloud floor because your constant-effect baubles aren't working until you re-equip things.
