Mutadaptive remote repair modules, like other Triglavian modules ramp their performance over time.
So, based on the stats, after a few cycles this “bugged” repairer is actually out performing the T2 - 744 HP/cycle compared to 512 HP/cycle at peak.
Compare the “Maximum Repair Multiplier Bonus” and “Repair Multiplier Bonus Per Cycle” and understand what they mean in practice.
There’s a balance reason the fittings are higher - the amount repaired, especially at peak is very high and in the sake of balance you’d want to force a compromise on the fitting. At peak, a pair of Triglavian Logistics Cruisers can out perform three Guardians, you need to push that down a bit by increasing the fitting costs.
Similar to Triglavian weapons - poor for the first few cycles, but one in their stride they are highly effective.
I’d say that was working fine.
