During the final boss encounter, if you die mid-phase, the boss despawns entirely and doesn't respawn unless you hard-reset the entire zone. That means reloading Kepler, dodging adds, and basically ramrodding your way back to the boss arena every single time. No checkpoint, no second chance. Just flower pods and frustration. This isn’t just a one-off: multiple Guardians are confirming the same experience over in this Reddit thread linked here: (https://www.reddit.com/r/DestinyTheGame/comments/1m3szl0/graviton_spike_catalyst_still_bugged_tz_33/). It's making solo completions feel borderline impossible unless you cheese movement or babysit your health bar like it owes you Glimmer. I’m not looking for hand-holding, just a fair fight. Graviton Spike deserves a clean finish, not a botanical limbo dance. Would love to see this addressed or at least acknowledged. Any other player out there struggling with this, feel free to echo your experience. Solidarity in suffering...or better yet, a hotfix.
