Stuck inside a PvP battle that I've already won

Title.
I attacked a guy, defeated him in battle and I was headed to an outpost to sell my hourglass. When I tried to sell it, it wouldn't let me and had this instead of the interact text : "Cannot end fighting for the Servants of the Flame whilist in a Battle". After this, I tried to opt for another match, thinking that maybe it could fix things, but the War map has this text : "Cannot use the War Map while already in a battle". We were fighting above Smuggler's Bay and I cannot see the "battle arena" there anymore either
