I already posted it in the Multiplayer help forum but I don't think I'd get as much support as if I were to post here. Me and my friend were playing the game fine yesterday and decided to call it a day, so we both left and I shut down the server. Today, when I turned on the server, my friend connected and said that parts of the map were gone and there were "black rifts" or something like that in random parts of the map. I tried connecting to see what was up but I get a message saying the save is incompatible and I need build23 for some reason. I tried that, but there isn't even an option for multiplayer on that from what I saw, so I pretty confused what the heck happened. My ports are fine as far as I know: UDP for 16261 - 16261 and TCP for 16262 - 16272 I even tried to allocate 4096Mb of RAM to the .bat for the server, still no luck. I reinstalled, etc. Anyone know what's going on?
