Dedicated server has the mods below and listed in order. My question is, is the mod order correct?
Clients can connect but not without restarts which leads me to believe that the mods on the server are in the incorrect order.
No. I put this on the workshop page, but LBPR needs to go after any mod that adds new placeables or buildings. Pickup + also has to be last after LBPR.
You also have a conflict between pickup and unlock plus with pick up. Need to choose one or the other.
