Excuse my vague title, because I could not find a better way to put it shortly.
I've encountered a few problems during the match, I hope I can explain it in a clear manner:

1. In the first picture, while on the left side of the 'true' map, the yellow team had the pylon, the 'minimap' at the top right corner of the screen showed the purple team had it.
In the second picture, there was the same problem.

2. In the first picture, when I hover my mouse over the yellow 'beam', it says that is my team. When I hovered it over the purple one, that said it was the enemy team.
However, as can be seen in the second picture, we were actually the purple team (because we lost).
So, to summarize, the colours were sometimes assigned to the wrong team. I hope this feedback helps!
