Build effects on all beams are broken, so when you... Or have been fixed, they were broken.

When you put a beam down in Experimental, the animation may or may not have played, but you would see the entire beam just kind of being like a little black box before its texture just pops into place.

Very unnaturally, very, I mean, buggily.

So the animation just went poof there somehow, as being fixed as well today.
