PortalDupeBegone
by fonnymunkey
PortalDupeBegone patches a Forge 1.12.2 duplication bug in which entities passing through a portal on the same tick as their death leave drops on both sides of the portal.
What it does
The mod targets the case where an entity takes tick damage at the same moment it crosses a portal, so its items can appear alive on the other side. The patch restores the vanilla 1.12.2 behavior, which some other mods can bring back. A config option, off by default, logs each time the fix triggers. PortalDupeBegone is published for Forge 1.12.2 only, and is released under the MIT License as open source.

I believe this behavior to be patched in Vanilla 1.12.2, but it appears that some mods can cause…
