While using Aether and Player Revive mod on version minecraft 1.19.2 (both mods are on newest version) upon leaving and rejoining a server a player is being revived instead of being killed. I have already infomred Aether team about this issue too.

This is a known issue and got fixed in newer minecraft versions. I do not support 1.19.2 anymore and I can only recommend to update to 1.21.1.
