What I need to know is if I log on now some 9+ hours later will the pigmen and their aggression level still be there or do things eventually reset?
My mistake was in the position I attacked from, by the portal stairs I killed what looked like a lone pigman with my bow while standing on a narrow peninsula over the lava lake. There was one hiding along the ledge I didn't see though, sent me flying off the edge and into the lava. I had a lot of fire protection gear on but it took like 20s to surface, and then there was no where for me to jump up so I had to break a spot. As soon as I jump up though another pigman falls on me and lands the killing blow.
I don't know how much of my stuff scattered and burned, but I spent 30 minutes doing suicide runs trying to get back to that one spot. Made it once but just immediately died again by the pigman that was camping the spot, but the next time I made it I was able to drop down and punch him into the lava first and immediately logged off after landing on my stuff. I was carrying all my best enchanted gear so I don't know what I salvaged, but if they remain hostile I have no where to move and will be dead in another second or two and more stuff probably falls into lava.
Either way I guess I'll have time to give it another run in an hour or two.
