I recently ran into the problem where targeted skills cannot be used-- they are greyed out-- which some players have reported in Imperial City. In my case, it was in the first area of Arx Corinium, where there are several lamia, serpents, and a couple of lurchers. I could use AoE skills to attack, but single-target skills were greyed out and could not be used, even if I were face-to-face with an enemy. The sounds were also missing from attacks.
It happened to me on PC EU, but when I entered the second area-- where you go through a short corridor and encounter three lamia before proceeding deeper into the dungeon-- everything started working normally again. At first I thought it was just a temporary positional desync of some kind, except in the first area I was still able to interact with the corpses to loot them, and could interact with treasure chests to pick the locks and loot them. Then I ran Arx Corinium on PC NA and experienced the exact same situation-- AoE attacks could be used (but were silent), whereas single-target skills were greyed out and unusable, yet I could loot corpses and interact with treasure chests, and everything went back to normal as soon as I went through the doorway/corridor to go deeper into the dungeon.
Has anyone else encountered this issue in Arx Corinium? I expect to be running the dungeon a few more times this month for the Golden Pursuits and will report back with any additional details, but was curious if it's just me or is happening to others.
I've fought mudcrabs more fearsome than me!
