I work extremely hard to ensure that all saves remain compatible with future versions, and in 99% of cases all saves remain compatible forever. However, sometimes things do go wrong (especially if the game wasn't saved in a "safe" area) so I can't guarantee anything unfortunately.
Same thing happened to me but i think might have better idea of what got affected , you see i made a save before going to church with chastity which was unaffected but one of my save that i made when making a choice between keeping the relic or destroy it got affected .
