Don't use common input hatches. Outputs may be common, but not input.
What's the distinction between input and output hatches? Also all RX are on MV output hatches. The TX was on another face of one of the output hatches but I moved it to a pipe because of weirdness. I'll try moving it to a hull instead.
MV hull has the same behavior. Same with an EV battery buffer.
Also all MV output hatches also have a pump on them if that matters.
