ROBLOX CRITICAL! UIGridConstraints broken

All of those UI constraints are broken in my game:

It worked fine, until either yesterday or today’s update.

^ Not sure if it’s just me (running Mac OS Sierra on MacBook Pro)

Also the first element in a UIListConstraint 's size does not properly update - as can be seen when you click on the OG Motel in the Blueprint GUI.
^ Pretty sure it’s everyone, as I had to manually call the :UpdateLayout() property due to complaints from many users. Also calling it is not convenient as I’m using tween service to tween animations, and only calling :UpdateLayout() at the end, meaning throughout the Tween, the UI looks bugged (of course it is).


I can confirm this. Robloxian High School just dropped 4 pages on popular because the very first menu that you are greeted with uses a UI constraint, making it invisible. You have to resize your window to fix it.

We are looking into this. Hopefully we will be able to find the cause and turn it off soon.


In the future a bug as intense as this should be flagged ROBLOXCRITICAL immediately because this has a dramatic impact on the front page.


It happend here to.

This should be fixed now.

  • Describe the bug. Describe what is happening when the bug occurs. Describe what you would normally expect to occur.

Because of this bug, the guis that is suppose to be in the window doesn’t show “load” boxes.
There were 6 gui’s with load slots.

  • How often does the bug happen (Everytime/sometimes/rarely)? What are the steps that reproduce the bug? Please list them in very high detail. Provide simple example places that exhibit the bug and provide description of what you believe should be the behavior.

Every time.

  • Where does the bug happen (www, gametest, etc) Is it level-specific? Is it game specific? Please post a link to the place that exhibits the issue.

  • Would a screenshot or video help describe it to someone? If so, post one.

  • When did the bug start happening? If we can tie it to a specific release that helps us figure out what we broke.

This bug just started happening, when the new client update came to me.
It was fine before the last update.

It seems to be working on IOS.

Devices tested on:
Windows 10, latest updates.
iPhone 6 latest ios.

I don’t think this part is fixed:

Gif to show how it is (first) and how it should be (second):

EDIT: (Elaboration)
The problem is with the proceeding elements shifting position, the sizing properly occurs but the shifting down of all the elements after “OG Motel” does not. I have to manually call :UpdateLayout() for this to happen which is why it pauses like that.

@TheGamer101 SEND HELP

do you animate this with TweenService? Is this a new issue as of the last day or so?

I do animate using TweenService.
This started occurring yesterday, previously it did not occur. And it ONLY occurs with the top element (OG Motel)
