## Round ID
36027

## Description of the bug
lack of ability buttons when you take over free xeno using the join as xeno button

## What's the difference with what should have happened?
should have buttons as usual

## How do we reproduce this bug?
1) have xeno that is free for taking becouse they ghosted
2) join cm and take control of the xeno using join as xeno button in lobby
3) no ui

- Note: It wasn't F12 issue

Reproduce round 36027's flow by taking a ghosted free xeno through the lobby's "join as xeno" button, then inspect the code handling that transition and the xeno ability UI. Done means the taken-over xeno has its usual ability buttons, without relying on the F12 key.
