So I have done at least 6 runs now to deep sea site 3 and the umbrella narrow, and still no unlocks.. I've been rank 20 for a while and can't seem to progress.. I've tried different combinations of shark / Unkiu.. Max Surv, Max Favor.. balanced.. Doesn't seem to make a difference... Is the RNG really that bad? Anyone else having trouble getting things unlocked? I've unlocked everything on airship voyages, never seemed to have trouble before this.
