Hello, i can reproduce this easily in 1.7.0.
As i work in QA let me actually describe the issue
When a player on king tier conquers a fief or if other vassals conquer a fief, the player can recruit a companion, and give him the fief directly.
note: the fief is given to the player as soon as its conquered
note: a voting procedure is in progress
Steps:1.
1. Conquer a fief
2. Go to tavern and recruit a companion if you dont have one already in party
3. Open chat window with companion in your party
4. Give the fief to the companion and promote it to noble
5. The voting happens for the fief
6. in my case the companion even though he already had the fief lost it via vote to another clan
Need anything else ?
