(Fairly new players on a vanilla campaign, no mods)

Seriously, this is making virtually every nest/wreck/beacon/etc. mission so much more annoying. Virtually every time we leave the sub someone gets an infection, and by the time we dock we've used up the 3-4 calyxanides we bought at the last station. It's a repeating cycle. Poor stays poor.

Is husk infection ever-present in the water everywhere or something? Are our dive suits made of paper?

UPDATE: Checked the server logs and didn't find any evidence of griefing - which makes sense since there's only 3 of us and we're all annoyed by this. I did, however, find that we ended up fighting Crawler Husks more often than not, in nearly every session. So this might be the explanation.
