Sometimes I finish a match and get exactly 0 XP,

As an extension from this thread: https://boards.na.leagueoflegends.com/en/c/gameplay-balance/Gd6WcXOj-sometimes-i-finish-a-match-and-get-exactly-0-xp

Basically, a couple times I've ended the match in seemingly 0 XP gain.

The symptoms is that at the end-game lobby the XP progression bar would stay un-moved after the match, indicating no gains. And if I quit out of the end-game lobby and view from the match history, the section that would note the XP gain on the match highlight would be straight up blank, if the match in question somehow received no XP gain after it'd ended. I also don't believe re-loading would solve the issue.

This may or may not be purely a visual bug, and may or may not be one-off with me and a handful of others being affected by this, but similarly it could also be a possibly significant bug that affects the XP progression and subsequently the BE gain for many players.

I would like the bug-fixers to look into this issue.
