I try to mend Clothing or other Items with Sewing-Kits, Duct-Tape, etc. in pristine Condition and get the Message 'i was able to mend the xxxxx' or something similar, but the actual Condition of the mended Item stays "Damaged" or "Badly damaged" as it was before Patching many Times. Sometimes randomly the Item Condition gets better one State, as it should, but that doesn't seem to work very often.
