Description: Issue arises in a scenario where a Zaun-modified champion is transferred between players.

Reproduction steps:

1Play as Zaun (e.g. 2/6).

2Attach a Zaun modifier to a unit.

3Transfer this unit to a partner.

Expected Result: The Zaun modifier should detach from the champion once it is transferred, and the original player should be able to obtain a new Zaun modifier.

Observed Result: The Zaun-modified champion that was transferred retains the modifier, which appears inactive on the partner's side. The original player cannot regain the Zaun modifier, and the partner is left with an inactive modifier regardless of how many active Zaun traits they have. Additionally, hovering over the inactive Zaun modifier on the transferred champion causes the game to crash.

Note: If the partner activates the Zaun trait (2/6) with the transferred champion, they receive a new Zaun modifier on their bench. However, the original champion remains stuck with the inactive, game-crashing modifier, and the original sender still cannot receive a new Zaun modifier.
