hmm sorry, I am quite sure that nothing else changed but I can't say it for sure.
You are right with the idols, most have the same icon and it could be that itemrack did not swap my sets properly (this happend in the past several times). I did not check this one when swapping items so this could be the thing that changed the score. My primary idol is the one I have equipped and my other idols in my bag have a different icon but I did not take a closer look at it.
Thank you for your effort. If I notice something like this again I will try to check all items first.
