*disregard - it's working now!*
Something new (and not good) this morning. I tried to login to my prim plus server (NA-PVE-Valguero-PrimPlusCrossArk4). Prim plus appears to load normally. The server selection screen comes up - I pick my server - and I get a disconnect message followed by a second message saying "Total Conversion Mismatch - relaunch game with proper mod?".
Hmm well I did as it suggested. It logged me in to my server but all my prim plus specific items are gone .. vaults, storage, workstation. My tames and the building looks intact but the rest is gone.
In an attempt to fix this I have done the following:
I have tried validating files .. didn't help
I tried launching with the Reset Total Conversion option .. nope
I tried removing and reinstalling the prim plus dlc .. that didn't work either
Possibly an issue with the patch that went in yesterday?
