Weirdness in game with SYSTEM

The game started with SYSTEM to move first. Three days after the game started, it suddenly became my turn. Even though SYSTEM, as always, didn't make a move. Also when I did notice it was my turn, all the time since the beginning of the game was charged to me.

It's a game of Havannah and I'm White, which means there's some record of me being the second player. But my move wasn't SWAP. I made what's recorded as the first move, placing a stone.

I sent this to Richard.

I’ve had this exact thing happen several times to me over the years, too.
