I was going to send in-game bug reports regarding these issues, but I also figured it wouldn't hurt to report the issues here on the forums since CS is likely not done granting Greymoor access to players and tearing their hair out from stress (assuming they have any hair left on their head, that is).
I'll try to be brief. All problems listed are what I've witnessed on PC-NA.
Problem 1: Some overland zones (mainly, Auridon) have had such bad latency/ping that collecting resources, fighting in combat, or sprinting takes several seconds of latency before registering.
Possible Cause: Auridon is allegedly where an OP Mythic piece of equipment is found, and in mad dashes to find that lead and recover said Mythic equipment, players are overloading the part of the server responsible for handling overland Auridon.
Specifics: I've had minimal issues with combat/resource collection in other zones, but Auridon is laggy as hell.
Solution: Avoid high population zones for now. Zeni is aware of this problem, however, and is investigating.
Problem 2: Sometimes when I enter a dig site area, the game does not register me as in the dig site area, even when my map clearly shows I'm in the dig site area.
Specifics: I've noticed that on some hunts for dig sites, the game will not register me as in the dig site area (and thus be unable to use the Antiquarian's Eye to find the dig site).
Workaround: /reloadui while in the dig site area causes the game to register that you actually in the dig site area, and upon finishing the reload, will temporarily fix the problem. Logging in and out also works, but only for that dig site. Scanning and repairing the game also works, but only to an extent.
That's all for now. If I discover anymore, I'll update this list.
If you can't handle the heat...stay out of the kitchen!
