Today, I was playing my last combat-orientated mission as a Champion, the FSC. Like the moron I am, I joined a now full Elite party. After the first depth, everyone but the leader and I called it quits, and us two quickly filled the slots with friends. After completing Charred Court (Depth 25), the party leader wanted to go and forge something, deputizing me to reinvite him when ready (This was Depth 26). He left, and some random person promptly joined. Though I felt rather guilty, I kicked the person, and eventually the party leader messaged me to reinvite him. But when I tried, I couldn't! I double-checked that the Open to Public box was checked, but I couldn't invite him.

Sadly, I took no screenshots. But has anyone else experienced this bug?
