Overnight, just a couple nights ago, my crew skill gathering times increased by 37%. My companions are all level 50. The time required for a Grade 11 scavenging mission went from 9m, 41s, up to 13m, 25s.
Why would this be? Nothing changed. I didn't switch guilds, etc.
At some point in the past I experienced a bug in which when I logged in, the same increase in gathering times was experienced. If I would teleport from one place to another, for example to the fleet and back to my ship, then it would go down to the shorter times. As of a couple of days ago, the change is persistent.
It's such a drag to take that much longer, I don't know if it will be worthwhile to continue using gathering missions to collect resources.
