In HQM New Heights (1.12.x-5.2.0Alpha1) the items are leaking into every creative tab, modded and vanilla.

Its actually just the reward bags in every tab.

This bug was fixed an hour after the release. It isn't it worth to put out a new one for only such an issue, but maybe you find one of the other new bugs too xd

This bug has not been fixed. It is still leaking the bags into every creative tab.
