Yes, but nearly all buildings/vehicles that consume Maintenance consume only 20% of their max consumption when idle, yet these are consuming the full amount. There could be exceptions, but these should be the last buildings they would want to make into exceptions given their likely use cases.
I mean stuff like Data Centers always consume the full amount, but that's because the logic for whether they are "idle" or not is not as clear since they can be utilized partially, instead of either fully or not at all.
But the same complications are not present with those buildings, and there's also no balance reason to make them exceptions - in fact, balance would favor keeping them in line.
@McRib Nevermind, it has already been fixed, at least for small Diesel Generator. Seriously these are W devs 👍
