Professor putricide ¿bug?

[Rojessiforo]

Hi, today i tanked icc25 with my guild and on putricide professor he got a kind of taunt inmunity on phase 3 that mess up the try... at the beginning was fine, but after both tank got 3 marks, we start getting problems because taunt cannot do anything says that he was inmune... iven death grip cannot do nothing.
This is normal? bug? or there is some kind of weird condition xd?
Greetings and thx

This is not a bug. Taunts have diminishing returns, meaning you can only taunt a certain amount of times before the boss becomes immune.
