If you complete the daily mission in Zana's Map and relog, you can't claim the reward in Zana's laboratory, as the portal in the Hideout is already closed.
Happened in a Necropolis map. The mission was to kill all corrupted mobs (blackguards). I cleared the map and it showed that the quest was complete. I didn't tp out of the map since i wanted to kill the boss first. When I realized that Merveil was hitting too hard I reloged. Back in the Hidout i couldn't get into the laboratory again. I also didnt get any reputation, as Zana was just about to reach level 4, which I was looking forward to.
