When ever I try to create a world using TerraCustom i always get this error:
Exception of type 'System.OutOfMemoryException' was thrown.
at Terraria.WorldGen.clearWorld()
at Terraria.WorldGen.do_worldGenCallBack(Object threadContext)
at Terraria.WorldGen.worldGenCallBack(Object threadContext)
EDIT: I tried it with just the normal settings but have it so it saves it in the tmodloader world folder and it worked for a couple of seconds then crashed with no error message!
EDIT2: I fixed it by disabling Large World Enabler and World Gen Viewer
