I played around with it a bit more, that looks like it's not working the same for the same chunks. moving something 16 blocks in any direction, rotating, moving something up and down all gives inconsistent results.
don't think anyone will help you there
i'm working since yesterday to get any help and i get nothing
i've even put WEB-682 up and i don't think i'll ever try to activate my game from now on
It is not duplicate of MC-108, I know how BUD works, that's actually working in much stranger way
