I'm going to bring this up again, because it also affects things like the Collector (for biosamples) which turns into a significant balance issue. Even in the fairly early game, a single Guar placed in a Collector lets you get 8.5 Biosamples for the cost of a single Bio-Container, which significantly reduces the early game Titanium cost of science.
I recognize that it wouldn't be practical to block Alien "Modules" from all miners, but would it be possible to block them from certain specific "burner miners" like the Collector?
