I think initially it was only affect a 1-2 cards but it seems to increasing its impact w/ each review day

My uneducated guess is that the tweaks being made to make the new mobile version of Image Occlusion work might be interfering w/ the existing functionality. All of my IO cards are created through desktop though. Of those, it appears to disproportionately (solely?) affect older Image occlusion decks. Stuff I created in the past month is good, but much older content regularly breaks.
