Is this a database issue?

It's an imported game

@A_0123456 or you could guess that the ending was black resigned, cause he could block the check with the knight

Yes @thibault it was an imported game, that's why it was showing "unknownFinish" This may be a database issue.

@Swapneel1 you can already tell there is a mate sequence going on so you dont have to wonder about the issue, you can just solve it by yourself

@JonathanChen @thibault @Swapneel1 Apparently, this is an entirely legit game...

Or the 365chess databases are messed up, but I doubt that.

”Unknown Finish” means, the type of the finish is not written down correctly in the PGN. I had this message lots of times, when I ipmported a game, where someone resigns

Unknown finish games can be eg:

lose during time
resignation
maybe a one beg for a draw and not accepted then left🙄
It's clear that the issue of game end is not determined, [because it's imported game]
Though I don't know if there is an option to specify how the game ended in such imported games.
Thanx
