A21.2 Zombies are not moving

[c4rboNN]

Hey, my server was created 2 days ago on my.gameservers.com and since yesterday night, zombies are not moving anymore, I've tried anything, I deleted all the Mods from the server but they're still not moving, but attacking u if u get close.

I put my logs there if anybody can help me thanks a lot:

It seems like your mods may have added assets that the save file can longer find. 

You'd have to add back the mods, or start a new unmodded world.

So log says it's running 21.2, but you have the 0_TFP_Harmony mod folder being loaded, which is from 1.0. Were you running 1.0 at some point? Need to delete the 0_TFP_Harmony folder so it doesn't load. May not be your only issue, but is causing issue according to the log.
