Closed NPC Duplicating?

NPC seems to be duplicating after I placed an Avian Spawner and Guard Spawner near my base which is next to an Avian colony.

They've become triplets and quadruplets.

Done.

 

Confirmed, and can be a terrible issue if you discover it too late, as it can simply lock up your world (we encountered an avian tomb on our server with over 1000 tomb zombies and skeletal birds).

 

Very strange. Documenting it right now. Is it only happening on server universes or does it happen on single-player as well?

 

I have been experiencing this as well, also on a multiplayer server with two players on Windows 7. The most I've seen so far of one NPC is five. It's happened with the guard spawner, doctor spawner and glitch spawner. The NPC spawners were placed in a deserted Apex village.

 

Confirmed to be still present in latest stable release......

 

Definitely still present. That makes eight of the same NPC.

 

Yea. There's a player on my server that have a secret area. It all started with 1 ponex which constantly duplicated itself when out of players fov. I first thought they dupe when there's a server restart but it seems to work like spawners. I killed 50 of them an left 1, after that there were 100 in a confined space.

 

I can confirm that too, some NPCs are duplicating to a point where it will lag up the server and outright crash it if we attempt to remove them by force.

 

Lets see how long it takes before this gets ugly : D

 

The glitch seems to happen when the world/area is unloaded and loaded again. I have a Floran castle that has a few sets of twins now.

 

And it goes on : D
