Have to say it’s rather frustrating how long this bug has been around. As said before it’s taking large chunks out of the game and in some areas making it unplayable. For example when playing on PS4 single player offline, I made my way to the volcano boss and for the second time, in a new playthrough, after beating the ghosts, the serpent boss didn’t spawn in. Literally wasted over half an hour standing around waiting. So I’m standing there, holding my sword, looking around like an idiot… Frustrating… Previously I was able to counteract this by using the admin panel to spawn in the boss and have a little scrap. But now, and for at least the last two weeks, I haven’t been able to progress in the story and beat the damn lizard. Can still spawn in the trapezohedron, but without fighting the boss there goes the enjoyment and achievement. Please fix your game. Lot of good areas, it’s an amazing game, but please, fix this sh#t.
