I am making a car system (yes no a-chassis) and I got this warning/error randomly too. It happens every time I sit in the vehicle seat of the car. It doesn’t break anything for me, but yeah I am also wondering what this means. It happened since I added disabling and enabling of the backpack core GUI when you sit in the vehicle seat (A person in one of the replies above suggests this cause of the error too), so I guess that might be a cause of this weird random warning/error.

Everyone, just wait it out until the issue is fixed. It shouldn’t take long, right?

I honestly have no idea what this could be, i only know that an “observable” is a common data type(class) that is used to literally “observe” a value, with the value’s own type. Here’s an example:
local myString: Observable<string> = "hello" -- implementantion in lua for example
Could this be related to the “observableValue undefined” warning?
Oh and by the way I’m getting this warning too

Same thing here. It threw me off also because I thought something in one of
my code had a problem. Source for it isn’t available too.
This has broken leaderstats for me. 2/3 won’t appear, and I’ve changed nothing since before this update. After this update, 2/3 of my leaderstats are no longer appearing and this is what I see in the output. Very concerned.
Affecting in game, not just in Studio too.

I don’t seem to have any functional issues, but I’m getting the message in output.
What is odd is that I’m getting most of them through pressing Esc (makes the roblox menu pop up of course). It’s odd since it wouldn’t have anything to do with my scripts. Pressing hotkeys for my UIS events don’t trigger it.
I also get this on an empty baseplate.
The Studio bugs that have been going on the past week are inexcusable. This other bug has been happening for damn near a week now, and now this one? This new one is breaking a lot of functions with player events, like PlayerAdded, CharacterAdded, etc. in Studio.
These recent bugs have been making it a pain in the ass to do any sort of testing in Studio, especially for when you need 2 or more players - you cannot do an in-Studio server test. I have to now use multiple devices on a live server to get that going.
Having this issue as well - CharactedAdded event is now non-functional!

Yep, I cannot run any code relating to when a player spawns in now. Re-wrote some code that is supposed to run when a player responds about 3 times before I noticed that weird output…
wow, that’s a lot of messages. i’ve only ever gotten one message as soon as i begin playtesting. super weird that different people are getting different amounts of messages.
this also might be why it’s somewhat related to PlayerAdded. maybe a value that determines if it’s a valid player or smth?
they mostly print when you mess around with the client side

the client side with physical objects, values, events (e.g.: CharacterAdded), or ui stuff?
