### Steps to reproduce

1. Have a user A in a project with permission to be assigned to work packages (e.g. Member).
2. Have a user B in the project without permission to be assigned to a work package (e.g. Reader).
3. Create a group that includes both users A and B.
4. Add the group with permission to be assigned to work packages to the project (e.g. Member).
5. Create an assignee board, add user A and B as columns to board.
6. Remove group from the project (therefore removing the permission from user B to be assigned to work packages).

### What is the buggy behavior?

* Column without assignee name shown (instead of name of user B).

### What is the expected behavior?

1. Column of user B should be Begin of the insertionconserved, with the title of the user remaining a link (to their user profile, as is the case today).
2. The users&#39; avatar is replaced by a dashed grey avatar (Grey 3, #878787) with a black user-missing icon.
3. On hover, the tooltip reads: &quot;This user has an unassignable role in this project&quot;
1. (a similar string [already exists in Crowdin:](https://crowdin.com/translate/openproject/8673/en-fr?filter=basic&value=0#797324) &quot;has an unassignable role.&quot;)

4. Similar problems exist when a user is removed from a project (in boards, work package lists, the form bit of details view and in Team planner); a separate ticket will be created to address this.
