Borderlands 4 One Fell Swoop Bug Fix Guide
The One Fell Swoop quest in Borderlands 4 has a frustrating bug where you can’t talk to Zadra, leaving the mission stuck. Players report the NPC has no collision and the quest marker just hangs. If you closed your game during the cutscene or mid-progress, this bug is especially likely to happen.
How to Fix One Fell Swoop Quest Bug
The most reliable fix is to create a new Vault Hunter, skip the prologue, load into the game, then restart. After that, log back into your original character. The cutscene should auto-trigger and push the quest forward.
If that doesn’t work, several other methods have helped players, including matchmaking resets, traveling through the waterfall cave, or progressing a nearby Vault objective. Below are all known fixes thus far.
Method 1: New Character Reset
Create a new Vault Hunter.
Skip the prologue.
Load into the game, then fully restart Borderlands 4.
Log back into your main character.
The Rush hologram and dialogue should play automatically, fixing the bug.
Tip: Don’t skip the beach cutscene when loading the new character. Many players report it only works if you let the scene run.
Method 2: Matchmaking Retry
From the main menu, select Matchmaking.
If nothing triggers, quit to menu and repeat.
Keep retrying until the dialogue plays and the mission moves forward.
This can take a few attempts, but has worked for stuck saves.
Method 3: Vault Progress Trigger
Some players progressed the bug by entering and leaving the Vault of Inceptus.
Collect three Vault Keys.
Beat the Vault of Inceptus.
Fast travel back to Zadra.
The mission should continue normally.
Method 4: Waterfall Cave Path
Instead of fast traveling directly to Zadra’s lab, go through the cave under the waterfall leading to her location. Entering this way can force the quest to update.
Method 5: Multiplayer Workarounds
Swap hosts if you were co-oping with friends on the same mission.
Join a friend who has completed the mission, replay the step, and your save should update.
Final Blurb
The One Fell Swoop bug in Borderlands 4 can be a game-breaking stop, but thankfully multiple fixes exist. The most common solution is the new character reset, while others succeed with matchmaking, alternate travel routes, or Vault progression.
Try these in order, and you should be able to get your run back on track without losing your save.
