In this attached game, a Raider has recently opened fire with its railguns against my Habitat space station. The Habitat is simply Ark Modules with "no armour" ticked and some CIWS + civ radar.
I would have expected that, with no armour, the railguns would make very short work of the Habitat (Habitat hull number 33 in game, the HAB-08 TG). . Instead the events simply report penetrating hits, with no crew lost, no damaged components, no ark modules broken.
So I think it's bugged that firing upon an unarmoured space station is not really causing any damage to the station.
I have one final bug to report, but I dont have a save file handy, although the orders are still in the TG history of TNK-01 in this save, happening around 2021.
I have another space station which is pretty much simply refueling hub + large fuel tanks.
And I have a ship which had a refueling system. The ship was ordered to refuel from a colony, travel to the station, and"Transfer Fuel to Refueling Hub".
The bug was that - with these orders on loop - I was filling the station more than 100%. I would have expected the task to fail when the station is filled, yet instead the tanker was transferring unlimited amounts to the station.
