Waterskins.

It can be argued that it should be possible to drink from buckets. I'm not entirely convince (it's uncivilized!), but I can see the argument. The greatest problem right now is that the implementation of fluid substances isn't exactly optimal, so it cannot easily be done in any generic way. Right now, it is the drinking vessels themselves, and not the substances, that define the actions that occur upon drinking. I'd like to fix this some time, but it isn't exactly my highest priority.

You should be perfectly able to fill your skin from a bucket, though. It has always worked for me. Just take the bucket and right-click the skin with it.

Hmm. That is strange. Maybe my clicks were off target, I attempted it several times. As soon as I get back to camp I will try again.

EDIT: Ah, I was clicking on the bucket with the water skin instead of on the water skin with the bucket. :3 Silly me.
