Halogen plays illegal moves

[Torom]

In a tournament, Halogen made illegal moves 4 times in 12 games and lost the games as a result. The tournament was played with Banksia under Linux. Threads: 8, Hash: 512, TC: 300+0.1, Syzygy 6-men, Halogen version is few days old without your last TC patch. All other engines had no problems. Let me know if you need more information.

Halogen seems to think in the first game after receiving the command

That a 3-fold repetition has occurred. Looking at the moves specifically "h2h3 f2f1 h3h2 f1f2 h2h3 f2f1 h3h2 f1f2" at the end It seems Halogen is right. Could you provide the PGN for the games? It seems this is actually an issue with Banksia

[Torom]

You're right, I hadn't looked closely at the PGN yet. All 4 games were 3-fold repetitions. Obviously a Banksia issue.

Game 3 is interesting, Halogen blundered an advantage of +16 on move 78 according to Stockfish. Probably because it had no more time, in that situation your new patch might have helped.
