Devices

Summary

Mutator Devices do not disable at all since v28.10 Update.
Once a Mutator Device has been enabled in-game, it either can’t be disbled, or it’s effects remain on the player.
In instances such as a “Pause Function” or when disallowing player movement for cinematics, the player will not regain movement as usual.

I have tried to disable Mutator Devices with Triggers, Timers and also Reference Devices, but to no avail.
I even tried setting up another Mutator Device with Default Movement Multiplier to enable afterward (to try and Override the 0% Device) but again, no avail.

Steps to Reproduce

  • Place a Mutator Zone with Movement Multiplier set to 0.
  • Set any device to Disable it after X period of time (Trigger, Timer, Button, Anything)
  • Play Game and Enter the Mutator Zone
  • Your Character will be unable to move as expected but when the mutator is disabled, you will remain frozen.

Expected Result

  • Player Movement returns to normal when the device disables.

Observed Result

  • Your Character will be unable to move.
  • When the mutator device is disabled you will remain stuck.

Platform(s)

PS5, but it’s consistent across the board.

Additional Notes

^ The above code was the one I received Bug Reports for, but my investigation led me to realise this affects literally 75% of my games. Basically any game that involves reducing player movement to 0% at any point, is broken.

The status of UCB-1193 incident has been moved from ‘Awaiting Validation’ to ‘Closed’. Resolution Reason: ‘Duplicate’

Can confirm that I also encountered this bug ytd, had to switch all my logics to use Stasis verse code function to freeze all players instead of using the MutatorZone :dizzy_face:.

I’m having this same issue. I was pretty confused until I saw this post.

Is it possible to use weapons while in stasis?

Yup, Same issue here…

Did you find solution?

Same and gets even worst sometimes as it randomly enables with no way back. Thanks for posting!

@Badllama85 @Fortnite_Tourney @g1-mag @Kawelo @BBHBOMJ Thank you for your report! Can you please re-post using the “New Issue” option on the Issues and Bug Reporting forums? Posts with this feature are connected directly into our development team so we can quickly get to them!

For more information, such as how to get the reference ID, please check out the article here: Using the Creative and UEFN Bug Reporting Form

Same. Weapons don’t shoot is another bug

Similarly, if “Sky dive volume” is turned off while the player is inside, the effect will not disappear and the glider will stay open forever.

I have and can confirm the same issue.

Still broken as of todays updates

Totally Broken. The mutator zone affect all the map

I wake up everyday to so many bug reports from people in my maps all saying “I can’t move” and I have to keep explaining “It’s not me honestly, it’s Fortnite” and I’m kinda sick of it to be honest… I have 26 active maps and I am not even exaggerating when I say 19 of them are broken because of this bug… Eyerolling so hard I can see my brain at this point…

Anyone looking for a solution that isn’t ideal can use this.
Setup a third person control device
Configure movement in third person device
Setup a volume device
Connect the two with events
You can successfully disable the third person control device

However, your controls will be ruined using this method since third person camera control use is intended to be used with the new camera devices.

We’ve had luck working around this issue by using TeleportTo in verse to move the mutator zone far under our map when we want to disable.

I have another workaround with a movement modulator. I just set the movement speed to 1.0 and activated it after I disabled the mutator zone.

Still not fixed? Can’t say I’m surprised anymore lol
