The Orochi equipment we use for analyzing filth in the Carpathian Fangs mission “Contagion” has a hidden cooldown timer of what I suspect are 15 seconds.
Given that the mission literally requires jumping into filth puddles to be able to use the analyzer at all, being unawares of the hidden cooldown timer can cause one to accrue a lot of debuff stacks without actually getting data.
Personally, I don’t actually care because I’m so overgeared I just waltz through the zmeu thereno matter how filthy I am.
Someone progressing through the story and actually running this ‘at level’ (i.e in appropriate gear, the tacked-on character level will be 50 regardless), on the other hand, may be massively hampered by this hidden cooldown timer through no ´fault of their own. (Nothing is telling them the gear isn’t ready for the next puddle, after all.)
Irrespective of whether this is actually a bug or technically a design flaw, it really should be changed.
