For some reason, when standing on top of, or in the way of the mana beams, they now pass through every single object -- even solid ones -- while ROTS is enabled. Try it with a gaia mana spreader for example.

This is until it gets out of range of the player (which is... I dont know how many blocks away) but one can tell it happens when the beam suddenly vanishes and stops emitting particles. When it reappears, it's open to hitting blocks again.

I take it, it's on TT's side then?
