something seems wrong with this game

Added checks on playing move so illegal moves won't be saved to db and results in error. There were already some checks but they were not sufficient.

Also added a flag on game table, so games with errors can be filtered out.

It is unclear why some illegal moves where inserted in the history (and some more moves afterward). I suspect some moves got registered properly in the UI but were not sent to the back end, resulting in de-synchronization between UI and backend.

Keeping the ticket open because it would be interesting to test all existing games in the db and flag them. Also filter them out from all lists (user data, etc.)
