I’ve got three wells with 2 O2 sabatiers each (6 total) connected to two pumps which feed into a single pump at my base. Pump 1 & 2 are outputting 15 units to pump 3, but pump 3 is only getting 7.5 l/h from each of the first two pumps. Unless there's an unlisted max input, I think it's more of a bug.
