If you check the version in the GUI, you’ll see 2964.00. Thats not Dragon 3.1.

I believe that Mr. Kaufman mentioned that he has a special version that play better at Chess324, so that could be version 2964.00

No, I have a special version that is better at giving handicaps. 2964 was just our latest dev. version, which we believe to be the best at standard chess, chess960, or chess324.

According to Plutie it was updated after game 154, but it is still playing horribly in Chess324 here is what he wrote
Current working theory - the bad performance so far would be because we submitted an untested branch which ended up having a pretty bad bug. whether that's actually why leela has performed so poorly remains to be seen, but it's the most probable explanation, considering the analysis I was running on the side during games with a known good version. - the playing Leela was updated to a fixed version around game 154.

for the record, that was a bit of a hasty statement - it's definitely still not fixed, but the update was for one bug that was found in the meantime. it's still possible to reproduce the issue with a few positions where leela blundered though.

this position is from game 166, leela went from an easily won position to a draw with 45.. Ng3. first image is from dag-bord-lf-se-2 - known working version, second is from dag-size, which was submitted.

The only decisive game against SF and Dragon that wasn’t inflicted by those two on each other was a win by Berserk against SF. A somewhat high exit, but still a win.

Even 52% vs 49% in some sense feels like fishy.
