Hi @Kafka
Sadly it is not only a visual glitch and it has been happening since the beginning of GW!
It would be awesome if your team could really work on it now and fix it.
I created a problem to report that bug in May 2017!
I also submitted some tickets in 2017 but gave up because it seemed that your team had no clue as to how to solve it.
In 2017 some battles were taken into account twice or not taken into account at all.
Now in 2020 it doesn’t seem that some battles are taken into account twice anymore. And I don’t think there are still people reporting that they start a GW day with a 0/1.
But there are still battles that are not taken into account at all. It happens to maybe half the guilds each week from what we can deduce by talking with other guilds.
When it happens the total of the 27 scores of the 27 best players is not equal to the total score of the guild.
As a consequence the final score that is taken account to determine the rankings can be wrong. And thus the rankings can be wrong.
