Ah. I should have asked you that in the first place. It seems the archive is packed incorrectly and I hid the update file! I can’t believe it! No one noticed this problem in over a year so thank you! I’ll fix it right away.
Fixed. This was quite the crazy oversight, the pack file uploaded was the wrong one. Now the pack contains the correct portraits with the correct range of sizes. Meanwhile, I need to double check all the other ones!
