Ludsoe, not sure if anyone has suggested a balance for the science lab yet, but I was thinking that requiring materials to study might help reduce the OP-ness of the module. I was thinking kinda-sorta like in real life where we actually either bring samples with us to space for testing or acquire them while we are there. You could create a new resource (samples, or whatev) and then make the lab empty on launch, and create a small-ish part to contain said samples, or maybe even build multiple kinds of samples, if you're feeling extra ambitious. Just a thought. Great mod so far, however, and I'm looking forward to seeing more options for science from Squad in the future updates.
