Yes, it does appear to be a bugfix. I downloaded again and the EXE files are different.

Yes, I started my UHO-Top15 testrun of Obsidian 8 yesterday and had 2 disconnects in some hundred games. The new binaries fixes the bug. Since yesterday evening, 2000 games were played with the new binary and no more disconnects...

Hi Stefan,

good news ... I had five time-outs after 400 games with v7.

Arcanum (New) 1.10 released
author: Lars Aurud (NOR)
https://github.com/LarsAur/Arcanum

Uses a SF net.

plays also without...otherwise I wouldn't have mentioned it (unlike some CCRL still tests)

Not yet, because of a bug. Fix imminent.

There is definitively a huge bug That needs to be fixed. Noticed that Arcanum start winning the match with 6 games in a row and later on it loses almost every single game, it simply start giving material away, like Rook and Queen with no reason, on move 25 instead of moving its Rook back to 25.Rd3, whereas 25.Re7? is a big Blunder, followed by even a greater Blunder 26.Qe4??

STOP it right NOW! Who do you think you are?, instead of saying something constructive, about the reported bug, you simply act like a BIG deal, you are the one polutting this Thread with nothing constructive. l. I am simply indicating and Pointing the Bug

[Gabor Szots]

There is definitively a huge bug That needs to be fixed. Noticed that Arcanum start winning the match with 6 games in a row and later on it loses almost every single game, it simply start giving material away, like Rook and Queen with no reason, on move 25 instead of moving its Rook back to 25.Rd3, whereas 25.Re7? is a big Blunder, followed by even a greater Blunder 26.Qe4??
