Well, I made it so all my TileEntities with negative Y Coords will:
- get automatically invalidated
- Y Coords set to 0, so they wont crash
- send a log warning for the first 10 times
- send a chat message whenever it happens for the first and tenth time in Singleplayer, so people might provide me with the Logs.
and all that whenever a GT6 TileEntity is set, loaded or saved.
