Noticed this the day before yesterday. Thought it's just my client going wonky and was too lazy to redownload, but now I hear other people are getting this as well.
Basically, when I drink water it'll still display 2.0/2.0l, when I bake pancakes it keeps displaying 10.0/10.0l of milk etc. Picking up the container and putting it back into inventory makes it display the correct amount, but it gets stuck on that as well (ie it'll stay 1.0/1.0l when I drink again).
