elaborate what u tested with, on sp or server? what mods etc?

We are not having this issue, The Center, Annunaki, PG, Elite Dragons, and others all running fine. I'd recommend redownloading any mods that were updated recently on the server.

Further tested and it was some issue with ACA not getting along with the mod. Was MP Sevrer on SE. Looks like they caught it on ACA's end. TY dev for response!
