well it would be counterproductive if i need a system to create the blockers, i created them with the correct 64*64 snap to grid, so position seem to be all correctly snapped,
i checked the position of the crossed block, (192, 320) this is correct
ill give you the capx, so maybe you can check what could be wrong or do further testing, no hurry really, its a sideproject tho im looking for a dependable solution, and this one seems very close...
