I've experienced strange issues on the PS3 when attempting Grand Company Leves ( is that how its spelled? ) for flame legion near dry bone on Adamantoise.

Basically I initiate the quest and there are mobs that are supposed to spawn with a card icon over there head. well on PS3 I sometimes have to wait for have the time to tick down before the mob will draw on my system so I can target him/her. The one instance there is only one mob that you have to kill and he keeps summoning adds until you kill him. level 20 quest. Well I know he spawn because I would be interupted doing things saying I was in battle, but there couldn't target anything... players aroound me had the same mobs spawn and were downing them, mine if spawned wasn't drawn and couln't be targeted.

So I loggout.. after running back to drybone because otherwise it wouldn't let me since I was supposedly in combat.

I login on the PC and retry the quest and it works instantly, not problems what so ever. almost the same time and network connection.

I encountered similar issues in there quests with late mob spaning but usually there are groups so I can just run to the next while the area i'm at redraws, but this one quest only has one mob so its impossible until he's drawn.
