Inconsistent timeout behavior in Tron

Experiencing what seems to be a bug in Tron.

I was getting timeout errors, which didn’t seem to make sense given my code (it’s not beautiful, but it’s also not expensive).

I decided to try “playing against myself” to see if the bug was determined by board position somehow. But I found a different answer; It’s apparently the “player 1” slot. Putting myself, or any other player, into the P1 slot for the game causes that player to get timeout errors after a few dozen turns. Put the same code into a different slot, and it runs just fine.

Is this something people are aware of? Is there a workaround? Are arena games impacted, or only test games?
