Freud Ring week 3 reward eats up 8-chair bags

The reward for week 3 of the Sylph Ring event includes an 8-chair bag.
Apparently, if you already had an 8-chair bag in use, it gets closed and all chairs in it are lost.

I don't know whether the same happens to 8-title holders.


Note that this is the weekly reward, not the daily one. The daily one is just the stone, and that is safe.
