The problem is, someone else attacked a zombie pigmen, while i was in the nether aswell, that person logged off, so all zombie pigmen turned on me, thats normal that happens all the time, but the strange thing is they never forget about me, they keep attacking me, this is going on for 3 days already, started in 1.8 pre3 and in 1.8 still remains, everytime i enter the nether they instantly turn on me and try to kill me, they seem to never forget it and actually stop attacking me.

im pretty sure that didnt happen in other versions, is that new, or is it really a bug? is someone else experiencing this?

So i tried going creative mode, which normally causes them to forget about you, when i went back to survival mode, they instantly turned on me again.
