MM Spawners Resetting - NOT FIXED in latest dev build.

Hey!

This is supposed to be fixed in the most recent dev build I was told on Discord by Lxlp - it appears it is not.

When setting up spawners they seem to reset after a couple restarts, inspecting the spawner file by downloading it, i see the mob type + locations are set to 0.

I have tried taking working spawner files, upload them to the server while it is shut down, then start it back up, works for 1-2 restarts, then suddenly resets.
