So, I need to ask because I don't see anything about this.

Has anyone noticed some sort of diminishing returns from doing the same mission over and over?

At the start of the Patch cycle I sent out about 2 Airships around sectors 6 and 13 to get Drav Motes. I got about 16 of them in total.

Now that our team has stopped doing Diadem and our last airship got to rank 50, I've been sending all 4 airships out and none of them has brought anything even remotely useful in about 2 weeks.

Every single time one of them comes back it's about the same log: "Violent Turbulence" over and over. Even our two slowest airships with high Retrieval/Survey are coming back almost empty-handed. All we're getting are Crafting Crystals basically.

I was going to call RNG on that for the first week but I haven't noticed a change in trend and I don't remember "Violent Turbulence" being so predominant before.
