3 years ago I'm seeing this in my modpack as well, though some rifts are moving sideways, not just down. setting the y-axis gravity to 0 made no difference on my end for them falling through blocks. #195 seems to be similar, though the rifts are actually moving here, and in their new position are eating new blocks. this is making the rifts significantly more punishing than they normally are, with them drifting off in random directions causing wanton destruction. Normally, they'd just sit on the surface of whatever contraption you are building, but now they are careening through them, wiping out sections and making automation much harder, since they will even drift through totally indestructible blocks, like compact machines, and damaging the structures inside.
Having both tc and vs at the same time, the rifts become strange - they twitch and fall. Changing Y-axis gravity from -9.8 to 0 can prevent rifts from falling, but they will still twitch.
