Woby drying rack is unaffected by acid rain

Both the items that are drying or their dried products are unaffected by acid rain (with big Woby) despite Woby's drying rack working with an inventory-like system.

On a similar note, acid rain does nothing to drying racks in the caves either, so that could be addressed too? Maybe just rot the item being dried if it's exposed to it for too long when drying, and accelerate the spoiling process if exposed to it while drying?

There's also other similar cases of the opposite happening, where acid rain affects things when it shouldn't, seen here.

Could maybe do something similar to what I suggested here for item moisture, to handle specific cases when in containers or so?
