Lawgiver ownership resets when it is turned into a snake

[Mouse]

The HoS's lawgiver got turned into a snake.  I helped kill the snake by punching, and accidentally picked it up when it reverted.  It then became "HoS Mouse Fitzgerald's Lawgiver".  I'm guessing this isn't intended behavior.

Unable to reproduce and also I have no idea how this could happen as the snake spell only moves the gun around and doesn't modify it in any way.
