As someone who gets 630 alot, they did improve timeouts for this game. Back at EP2 you'd only need to "timeout" for 2 seconds for 630 to pop out, now it's like around 60-120 secs (can't remember the exact number).

That being said, a rejoin UQ/AQ mechanic would still be nice, even if I have to pay meseta do to it.

I tried using Client Orders > Orders That Can Be Accepted in the Fields of Ongoing Quests for Request IV but it doesn't work for some reason. While this is a minor bug, it does annoy me since 40k EXP is a bit plentiful...

PS: The Quest I took is Ruins Expedition (SH) and the pebbles drop when I took the CO.
