Wotg solyn issues

Me and my friends have a calamity server with WoTg, after skeletron solyn landed as usual but never moved in and disappeared after that. I summoner her back in with cheat sheet, and she’s still yet to move in or do a camp, though it hasn’t been very long. We have calamity overhaul.

Tried loading up a multiplayer world and it didn't work, so I tried again and it now says 'unknown world' and just says starting server in multiplayer and says load failed in singleplayer. Any help is greatly appreciated.
