Sorry, I'm not 100% sure, but the new update may have broken the in game sprites.
I tried this mod for the first time today and only the Formation screen sprites were changed, and in battle sprites were base sprites. I thought this was due to complications with animations, but after looking at some videos, I realized the in battle sprites should be changed as well. I patched using the older build (CCP2ndBeta-2021.rar) and after opening my old save file, so far it seems like all the sprites are correctly changed.
