Some Repair Functions not working as intended

Some items that take just damage over time as wear and tear are not repairing as they should.  The items that I have noted that are having issues (just the ones I have found) are:

Carpet

Drapes

Scroll

Might be others just the ones that I have enountered.  The builder will spend a near eternity whacking away at the item and it will like once a day or two tick up one HP, but will never actually repair.  Normally items get whacked like 2-5 times (like hour?) and boom they hit full hp, these don't behave that way.
