Spells: Potion of Antibody not working anymore

[Nedala]

Copied this from technical discussion (since i found out im not the only person with this problem):

So since the last patch minor potion of antibody (maybe other potions too, i didnt try) is not working correctly for me. I get like 1 cha, and 1 DR out of it only, but it worked for other people. Any ideas what that could be?

Edit: tested it further: i get 5 cha and 5 DR, but after like 20 secs it drops for 4 DR and cha, so i end up getting 1 cha/dr.
