This would have been about 8 hours ago on Figaro. I was doing leve quests in the Nanawa mines with one other person.

We had an issue where, on a number of occasions, one of us would see the other person's HP and MP listed as ??? as if they were far away, except we were standing next to each other.

We were able to target each other with the cursor, browse the bazaar, check equipment, etc. But we could not engage in any combat actions with them, such as healing or buff spells.

We found the only solution was to disband the party and re-invite, which solved the problem, although it created complications mid-guildleve. The problem repeated itself about half a dozen times during the night. Often, it coincided with returning to the nanawa mines aetherial gate after dying. While I couldn't be certain, it may have been related to the fact that we were long-distance separated, but the game not recognizing our re-unification properly.
