Powerdrain beams still half-broken

[Stakhanov]

While the new half-drain mechanic seems to work as intended , powerdrain beams remain very glitchy. While it's bothersome that they do not display any stats under the Weapons menu , they often fail to drain anything (even in singleplayer) despite the beam connecting with a target that takes the entire screen. This is sometimes (but not always) fixed by changing the powerdrain computer's weapon number.
