Studio auto selects every instance outputted in a single print statement. This is happening from my script that prints several instances within a single model. The included video highlights my issue exactly.
Expected behavior
Clicking on one instance should only select the instance you clicked. Not all of them.

Thanks for the report! We’ll follow up when we have an update for you.
The video shows off our confidential game code and structure, where I was able to repro it. Have sent it as a private DM to Roblox staff.
Got this repo while working with @Usering this only reproduces in scripts running in the game.
print("Got", workspace.SpawnLocation, "in", workspace.SpawnLocation.Decal)
Put this in a script on workspace, and play the game on server and client mode.
I got a fix in for this, it should ship early January after we’re back from the break.
The behavior I chose is to select only the single Instance, and also not focus the script. Now you can pick whether to open the script or select an Instance depending on whether you click the Instance link or plaintext part of the output, does that sound like the best solution?
Yes that sounds ideal. Thanks for the patch!
