I experienced the same bug in both the release and the updated version.

When trying to eat or drink items directly from the floor, the character puts away the item currently in hand, but does not take the item from the ground. This results in the item still being on the floor, but the character being set to "currently eating/drinking" which never stops.

It seems as if there is a problem with taking an item into hand that is not in the inventory.

After the failed attempt to eat/drink from the ground, any attempt to eat or drink an item from my inventory would result in "you are already eating/drinking something" which would only go away with a relog.

I have tried to reproduce it after the recent patch and it still seems to be a problem.
