Pixelmon Statues/NPCS Despawn (Latest Sponge Build)

So i always believe in running the latest versions of Sponge to help the team of Sponge make updates to fix issues rather then running old build versions that doesn’t help anyone. So Please don’t reply to this telling me to use an Old build. I’d rather new builds come out with fixes then rely on old builds.

On to the Issue:
In the latest sponge build when using the NPC Editor & Chisel to create statues, or shopkeepers/trainers upon server restart; the npcs and statues are removed from the world.
I’m not sure what the cause is exactly, they just get removed. Its not an issue with pixelmon because it works fine without sponge.
Note:
Sponge Build: spongeforge-1.10.2-2123-5.1.0-BETA-1928.jar
Forge Version: 12.18.2.2132

Oh there are issues with SF on forge’s website. Grab the latest SF build from this website under downloads and try again.

Does it actually solve entity despawning? Pixelmon marks these as permanent, and from OP’s report it does work fine without SF. Looking into the changelog, there is nothing on entities or chunk unload… Could be wrong of course, I only checked the changelog in the downloads page.

This didn’t happen with SF 1928 and does not happen with SF 1952. (Running Pixelmon 5 Beta 12 aswell)
Running any sponge plugins? If you disable spawning, npcs are getting deleted.
