Some bugs in Chess in mac os 10.13.4
Seems like it is spawning Pawns out of nowhere
First it spawned one at C2, which I took with my bishop...
Then it did that again spawning another at G3...
Then on taking king back to G1, it restored it' pawn and moved to F2 😳
After a couple moves, it spawns another Queen!!! 😢
