Yeah, the recipe alert is never showing up.
No, It show up individually, but I saw that this happens only some times.
Ah ok, I don't know that. So thanks for help and sorry for this big waste of time. Bye!
So spider, zombies and all the hostile mobs aren't affected? I think that they are affected too.
So first sorry for my absence, I was so busy with school and my family. So I post here two gifs, where in the first you can see I used a poison potion on a cow and a skeleton. How you can see the cow suffers the damage, but the skeleton don't produces particles, so it doesn't is affected. In the second one, you can see i throw a speed potion and this time the skeleton produces particles as the cow do. I'm in the version 1.9, but I think you've already resolved this bug. So sorry for the eventual waste of time and thanks you for your help.
