When using a shrinking device from compact machines mod to get inside a machine, while wearing the ring my max health is increasing by a bar or two, to the point that I thought that the ring is supposed to give you health bars until it turns white, however after that the health bar glitches as seen in the picture. I am not sure if the issue is from botania or CM doing something however the end result is increase in max health. This happens in Botania version 187, forge 10.13.3.1389 Compact Machines 1.7.10-1.19-fluids-preview-b5.

Edit: Ok it may be some weird combination of mods at work. I have just run an instance with the two mods and nei on forge 1401 and the bug did not occur.
