This happens to me on my Windows PC. Roblox hasn’t fixed this bug along with the bug that prevents you from changing UserInputService.MouseBehavior to Enum.MouseBehavior.LockCenter, so I wouldn’t recommend using the test server until both of these issues are fixed.
Has been happening for several months now.
This is still occurring, happens on my PC running Windows 10.
Thanks for the report! We’ll follow up when we have an update for you.
Hey this still seems to be occurring. Is this QOL fix scheduled to be patched any time soon?
Bringing this back up. The process of cleaning up test servers has been significantly sped up, but this bug is still present.
Can confirm that this is still an issue. Been having this issue for months now and it still usually happens.
THIS IS STILL AN ISSUE, AND STILL INCREDIBLY ANNOYING.
When will this be fixed? Bump.
Can this issue PLEASE get fixed, I’m literally begging.
From what I have found, it seems that if you cleanup the client, then just that client closes. If you want to clean everything up, click on the cleanup button in the main window where you started the test from. That will cleanup the server and all clients.
However, with that being said, there is a bug. If you close the individual clients, sometimes on subsequent tests if you hit the cleanup button on the main window, it will close the server but not the clients. You have to manually close the clients. The only way to recover from this is to restart studio. That’s been my observation, and that is a bug.
In the past, however (prior to 2022) Cleanup would close all instances of the local test.
bumping this again. I have no idea how this is not fixed yet. Please, This bug is very annoying.
Very annoying bug, PLEASE fix!
Hey Roblox, this is still an issue, please fix it.
Still occurring in March of 2024
Wow, I didn’t even know there was a forum post for this. This issue has frustrated me for years now, and I never got around to actually making a report for it. Now that Studio is down (again 
) I actually made my way over to the forum and saw this!
I don’t believe this is intended behavior. As far as I know, if you press the CleanUp button from anyone of the clients, it shuts down the hosting server, but not all the clients. Then you have to close them all individually. You can close a single client by just closing the window. CleanUp button should ALWAYS clean up ALL test windows.
Roblox fix this pls : D
Hey there,
An attempt to fix this issue has been released (and turned on) if you are using the latest Studio.
Let me know if you are still experiencing this issue or not.
Thanks
It appears to fix the game:BindToClose/Players.PlayerRemoving issue in this post: Local Server Test doesn't properly cleanup when the Cleanup buttton in the original window is pressed
However, if you specifically click the Cleanup button in the Server window, the client windows do not close.
I verified that I am on version 619.
it used to actually close the server and all client windows. i seriously doubt they intended to remove that useful functionality to instead add another alt-f4
Still experiencing this issue, in my experience it’s slightly different to other people’s description of how it works but seems to vary even for me. It starts off working as intended and then eventually you click Cleanup and it greys out and doesn’t close any windows. Still unsure what triggers it I will edit/respond again if I figure out the steps
Still experiencing this as well.
