Right...
ill make sure to check that

On your video, specifically on the "items that change Isaac's look" note, most of my mods combat that particular issue very easily! You can look through my basic character commissions to get an idea, but basically (assuming you have a main.lua file and know the basics) create a function you call on for most instances in which your character's look would get changed. player:GetCollectibleCount() works perfect for this. Every time it changes, call upon that function which contains player:ClearCostumes(). If you have any questions, add me and I'd love to help you out!

For a character with no gimmicks or custom stuff, this mod has a lot of charm, I love it.
