Swiss System Tournament Bugs and fixes

There are some issues with the Swiss tournaments.

I have run about twenty events so far and these are serious.

Before I go on , I want to thank Lichess for creating the Swiss feature , it's absolutely cool.

First of all for some reason when games start sometimes some of the pieces are missing from the original position.
Often there are no knights for one side visible.

I often have to change tabs and reopen the game to get the board to display correctly.

More importantly we have a major Swiss pairing issue.

The Lichess pairing system is pairing the rounds by seeding the players according to their tiebreaks during the ongoing tournament.

This is not okay. Pairings must be made solely based on points firstly and then by rating.

You do not do pairings taking ongoing tiebreaks into consideration.

Tiebreak or bucholtz system or whatever is strictly meant for determining final ranking and or prize place.

Please consider fixing this issue !

If you watch some of sladgie's videos, you can see these bugs play out and what was going on before and after the board shows up without pieces, pairings wrong, etc. My personal favorite was the one with the red ufo showing on the last video, it was kind of neat. :)

#1 Thanks, I recorded github.com/ornicar/lila/issues/7353

For missing knights, use a modern browser.

Pairings are handled by github.com/BieremaBoyzProgramming/bbpPairings which implements the official FIDE dutch system.

I don't understand after supporting the site every month for over a year I have to get sarcastic answers when I post one legitimate question. WTF.

The pairings are illegal , any tournament director or International Grandmaster can confirm that, but obviously you don't care. I totally get it.

Thanks for your help.

Sorry, I was not thinking clearly when responding to your question and need to retract my previous answer.

But now I am in a position where any answer I can provide will offend either the developers or the players... I will look further into this; if nobody paused (or quit) or latejoined I should be able to reproduce the pairing conditions and audit the accuracy of the pairing software (which I believe to be accurate). If players did join, quit, etc. it's going to be a mess to audit but I can figure that out too.

You don't get special treatment just because you donate to the site. Toad is trying to help, you don't have to be so passive-aggressive.

Hello,

Could you post a link to a tournament for which you consider the pairings are wrong?
