- Offset structures by minus half their width in x/z (as well as the usual +8), so they can't ever spill out of the 2x2 chunk area being generated (provided they are less than 16 blocks wide, which mine are) - Pass the block placement flags 16 | 2 to Template#addBlocksToWorld instead of just 2, to prevent neighbour updates - Ignore unloaded blocks when removing floating trees (in theory there can't be trees there anyway)
