[1.20.1 - Version 0.3.3] I play with the essential mod. When entering the dimension, whoever entered can no longer take damage and mobs no longer target them. The experience bar is reset upon entering and exiting the dimension. The sky does not change colors to show a day and night cycle, so using items or blocks that rely on daylight is not easy because clocks don't show when it's day. Beds and portals to other dimensions (Nether, Aether, etc..) do not work when inside the dimension. I can provide more details or stream the issues over discord or something if needed.

Edit: I tried to post this on curseforge, but it kept giving me an error, hopefully this isn't too inconvenient.

Hello, no problem, indeed the damage, xp and day night cycle are deactivated, but the creation of portal is not blocked I think, it must be a bug, I searched on my side and there was no problem, I do not understand why, it must come from compatibility with other mod, I will try to correct this in a future update.
