At the moment, the only beam weapon in the game is the K kit for the Idris. In one patch it's OP, in another patch it doesn't seem to hit anything and do any damage. What's been going on with the Idris laser?
TL;DRFixes improved the Idris laser's hit registration and a bug in passing damage up the ship hierarchy, but other quirks remain; developers know the cause and are looking for an elegant solution.
I can't remember if it was late in 4.7.2 or in 4.8 PTU, but there were some fixes done that improved the hit registration of it. And also there was a bug where if you hit an attached item, say a door, such as the front of the Idris, which is all doors, it was not correctly passing damage up the ship. That's now fixed in 4.8, but there are still some other quirks regarding it not correctly doing damage.
It's almost the inverse of the command module thing. The command module, we need it to pass damage, and this one it wasn't.
Both of them are sort of torturously related, in that it's failing to pass damage in the correct way up and down the hierarchy. But people are working on it. They know what is wrong with it. It's just trying to find an elegant solution. Like most game development, in any studio, you fix one thing, doesn't mean you don't make two other issues.
