I noticed a bug, and I wanted to mention it before I forgot.
After I got the third Kin, this message keeps popping up whenever I try to talk with a Kin.
Warning: write error: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing.
I can still talk with them, and the message only stays there for a couple seconds, but still wanted to make you aware of it.
! EDITED !
