ok so i was doing a x-realm kill on another server (pve) and lost my flag when i returned to my own server flag still gone.
i wanted to make a pic for proof but any method i would use would expose the realm i play on which i would rather not do.
1. get invite to PVE realm
2. wait till flag comes off
3. leave group
4. flag still gone
all the opposite faction on my server all come up yellow and cant attack me i stood out in the open away from guards taunting people with emotes no one could attack me.
i haven't fully tested it yet i haven't left the isle but i have explored a bit went into a different area of the isle and flag stayed off.
ile keep testing and report back with anything extra i find.
EDIT: death from random animals got me re flagged so did leaving the island.
