Also, any idea why now drinking from a can full of antidote liquid won't cure leprosy?
That's sadly a side-effect of the new [T]aste command. You used to take half a litre from the bottle in a single gulp, but now you drink by smaller amounts. However antidote curse you with a percent chance based on amount ingested - so instead of one high chance for a single huge gulp, you get several low chances for multiple smaller gulps. As far as probability goes, you are less likely to have your leprosy cured, so we should have a look at the percentages and fix it.
