I have finally fixed Element (I fixed it 12 hours ago, but I forgot to send the message).

The issue was a threefold issue. I have adjusted the message again so Element should still move even if something goes wrong.

Edit : Another issue found, that has been fixed as well.

I might as well make this useful

What would everyone say is the single biggest bug that made it into a stable version of your engine? Mine is (of course) the bugs in v1.4.10.3 that cost it a tournament win. I should have simply imported v1.4.10.2.1 into Stable Element before leaving.

Me it’s a bug (I don’t have the version) where it pruned branches completely randomly (one of the first versions), which made it lose pieces in a random way

The Biggest Bug in Scurious was, that it completely disregarded its PieceSquare Table, causing it to move its Queen very often, It was In scurious until 2.2. I now had to change it, so Scurious doesnt update the PST incrementially anymore.

Good question! For me that would be the bug that caused Shallow Blue to blunder it's queen that one time against Scurious during the last 960 tournament. though I have to admit I never really figured out what part of the code didn't work, I just reimplemented all the new code into an older version and that ended up working perfectly lol
