Cannot create nor leave party

Hello,
I was planning to do Tanren Mansion with my guildmates but when I want to create party it doesn’t say that I created the party, and when I try to leave party I don’t get the message saying I am removed either. And when I try to join my guilmate’s party, it says that I am already in a party even though I have done /leaveparty. Precisely I am outside of the dungeon. I am still in the overworld.
Please take note of that issue and fix it.

There was a problem with the party system earlier. It’s been fixed since then.

If this even occurs again try re logging or refreshing.
