Description
Patches an issue where entities can go through portals but take a tick of damage at the same exact time, causing them to both drop their items, and show up alive on the other side of the portal with a second set of items.
I believe this behavior to be patched in Vanilla 1.12.2, but it appears that some mods can cause the behavior to reappear.
Can optionally log instances of this happening, turned off by default in the config.
Only needed on the server side.
Created for use in the RLCraft modpack.
