When i enter the 3rd type of overlay, hunger dissapears and when i enter the Nether Portal the animations are canceled. Those bugs dont occur while OpenCubicChunks is hidden. Here is a video

Thanks for reporting the issue. This will be fixed in the next release of the mod.

It should be fixed in version 1.18.10: https://www.curseforge.com/minecraft/mc-mods/more-overlays-updated/files/3099374
