[Fixed]Level Sequence Event Duplicate Bug

Level sequence appears to execute events 2 times.

Edit: At last! After what seemed forever they fixed it!!

Hi SwordSkill,

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this error on my end?
  • Can you show me a screenshot of your level sequence script?
  • Are you calling the level sequence in multiple sources or is it only called in one location?

Hi SwordSkill,

We have not heard from you in several days. I am marking this as answered for tracking purposes. If you are still experiencing this error, please comment with the requested information.

  1. Yes
  2. Make an event with Level Sequence and run it.
  3. No need.
  4. No, only from one source and double checked it on a clean project, more than once.

This is ridiculous, there seems to be a problem with my internet connection didn’t seem to send the message, so I tried again.

So this occurs if you have a level sequence and the sequencer runs an event. Even if the event is something as simple as a print string the sequencer will run in twice in a row? When are you calling the sequencer? Is it on begin play? On level load? On tick? What are the exact steps you are taking when using the sequencer that experience this result?

Saw this today. sequence was already set up, added some basic events to start/stop a sound in blueprints.

in the starting sequence, the event that existed at 5s only fired once. Added a new sequence at 5.166667 and the event fired twice.

Tried setting the snap from 30fps to 60fps, no change in behavior.

Same thing occurred in the ending sequence (with timing marks 1.4 (also tried 1.0) doubling and 5 single fire)

Breakpoint hits twice. Printstring printed twice.

sequence is fired well into the level on top of other gameplay logic.

Pared down our project to the minimum repro:

occurs in 4.12.5

opening in 4.13, the issue does not occur.

Try using Print Strings, can you tell me if it fires twice?
Level Sequence is relatively new feature meant to replace the Matinee.

I have not been able to reproduce this on my end. Is it possible that your event is getting called twice?

No, I did it on a clean project and formatted my pc for that exact reason cause previously I had many malwares so I thought they were interfering with the process but after the wipe, it still does the same.

Hi everyone,

It looks like this issue was fixed in the latest engine version, try updating to 4.13 and see if you still see the error. For additional information, please check here.

Yes, at last!!! It has been fixed oh my god!!!
It’s been like forever!!!
I gave up after 4.10 due to massive bugs with Rotation and stuff.
Hopefully they are gonna fix more bugs :slight_smile:
