Portal Anchor

Portal Anchor

Portal Anchor fixes a niche but painful vanilla server issue: mobs can disappear after going through a Nether portal if they arrive in a dimension where players exist, but are very far away.

That can break portal-based farms, especially setups that move mobs between the Overworld and the Nether.

This mod gives mobs a short grace window after dimension travel so they do not instantly despawn just because the nearest player is far away.

Good to know

• Works server-side.
• Players do not need to install it on their client.
• Also works in singleplayer.
• Intended for portal farms and technical survival servers.
• Does not add blocks, items, mobs, or worldgen.
