Brand new save, On the apocalypse setting, spawned in Muldraugh, Unemployed with no positive or negative traits, Modified character to include additional rippable items to simplify the test; Chosen items being Long Socks, Long Skirt, Long Sleeve T-Shirt, Formal Shirt, and Tank Top.
Unequipped all clothing, Favorited the Long Skirt. Right clicked on the Long Socks, and went to the Rip Clothing option; The Long Skirt is shown within the list of rippable items, and is calculated into the Rip all function, showing that 5 items would be ripped if I did it; I have 5 rippable items as listed above.
Began the ripping process, And all 5 items were ripped, including the favorited Long Skirt.
Screenshots included demonstrating all items uneqipped+Long Skirt favorited, Right clicked long socks with the expanded menu showing the rip clothing count+long skirt being shown, and the result after running the ripping process showing no clothing remaining, not even the favorited one.
Bug exists and is reproducible in a fully unmodded and freshly verified game as of b41.47 IWBUMS
