As of the rewriting of the Stats some effects are showing a strange behaviour on some challenge checkers.
For example:
https://project-gc.com/Challenges/GCAFDJQ/81866
It runs as good as before, but any icon at the start of a row seems to be min. 4 times the size it was before.
I can provide a screenshot of how the result of that particular checker was before.
Tried on different PCs with different browsers and different sizing of the browsers etc.
