Oh man, I dunno maybe it's just the PS4 version, but the glitches we've encounter just suck. I was playing with 2 others, and they dueled, after which one of them would float in the air!! We were on Sanctuary at the time, so the roof prevented him from going up too far, we fast traveled to a city area thinking that would clear it, but nope. He could walk around VERY slowly, but when he would jump, he literally would float up and up and up into the map til we could see him!! He could ground pound and come back down to earth, again moving VERY slowly, but as soon as he'd jump...up up and away! I've also had quest where I needed to collect 5 things, but only 4 ever showed up forcing me to quit and go back back into the game, and I've also experienced NPC getting caught in a dialog loop where they just keep repeating the same clip over and over and over regardless what quest I switch to. Not to mention just over all lagging sometimes. even when playing solo. Just bad stuff that is really disappointing because as you pointed out, it seem so unusual since the Borderlands in the past have been pretty solid titles.
