I currently know of 3 bugs, in Destiny 2 Planets, the planet I picked up wasn’t the one the game tried to swap over, seemingly random, happened to multiple players in my run(s)
In Planets, the 3rd damage plate’s buff just ends early (don’t exactly know if this is a bug or an invisible timer ending the whole dmg phase early)
In Golgoroth, shooting his back sometimes gives you dmg numbers but not the gaze for whatever reason (was getting it with the same weapon each time, and even multiple shots didn’t work)
