Yeah the whole inventory thing is borked on HZD even on console. It's just borked. Yet I dearly love the game. However Guerilla did a huge mistake. You should have been put back on the map post battle not before the last mission. They missed a huge emotional score by having Aloy visit Rost's grave after the battle and not just before it if you happen to discover it. Such a missed opportunity and silly world building there. Tell Me Why is good, just had chapter 2 install. Steam is also borked why can't you keep playing while stuff downloads, other platforms manage to do this with ease.
