Further you can't teleport your crew into that room as it is not physically selectable, there is virtually no space you can click on to target weapons or beam crew.

It usually just moves them to room with the lowest ID (like it does when boarding the flagship weapons rooms with more than two individuals). Attack drones indeed can't hit the systems, their shots connect with the rooms around it and deal their damage there. The drone targeting bug was caused by something somehow different.
I tried to fixed this indeed quite annoying visual problems. The Auto Drone Habor also should be targeted correctly by your drones now.

It appears the ships with roomless systems cause quite some instability. While I got them to work ingame on some point, the game later started to crash on load. KartoFlane mentioned he had similar experience with 0x0 rooms. Not sure if this is going to work out in the end.

Sometimes the error checker implies that the rooms cause syntax errors, but at first it didn't... No idea what is going on with that.
