Now I know, this is a hell of a necro, but it directly follows an unanswered question of this thread, and the problem is current.
Is there any way to fix the stacking model collision bug without a qvm download? Can we re-align the BBOXes ?
On a related note, with this patch applied to a qvm, a friend of mine managed to build an upside-down telenode (i.e. spawn bits in the sky, blue stuff touching the floor) How the hell could this be possible without some sort of brush or similar for a buildable surface to have it to cling to? It was in ATCS, in human base, btw. Right in the center.
