Has anyone had issues relating to map data not being saved for players with large worlds? We have a 20000x6000 world, multiplayer over LAN and it was working fine for a while but we suddenly started having issues with map data not being saved. Reinstalled both Vanilla and modded and its still happening. No cloud saves or antivirus messing with it during saves. On logging off it says receiving tile data instead of saving map data. It will occasionally save it, but its unpredictable.
