Description
This card is Zetrith Multiplayer 0.11.5 for RimWorld 1.6, Workshop 2606448745, default UDP 30502. RimWorld Together (Workshop 3005289691) is a different net stack. Both loaded = desync city. Host and guests match 1.6 + the same MP build. Firewall blocks on 30502 look like “waiting for players” forever.
