MCEdit did nothing unfortunately. Didn't ruin mod blocks on the other hand, which was a nice surprise. Gonna test WorldEdit later today, though I'm skeptical. And tired of this crap
Have you been able to reproduce this issue in creative? I'm personally at a loss as to why this ishappening. It makes me wonder if it's a glitch with destroying the filler while it has a non-placeable block inside it (and not specifically the grav-gun).
