ServerScripts cause issues on GUIs

[LazVaz12]

Using a serverscript to detect a mouse click on a gui doesn't work. Also, applydescription doesn't return classic clothing, faces, or bundles at all. It also throws some errors.

The 27112 ID's are Robloxian 2.0, 2041 is the Err... face, and 128 and 139 are classic clothing. I tested other clothing too, seems to be a global issue.

Try enabling FFlagPromptsAllowButtonEventsOnServer and let me know if anything changes.

@Windows81 It's already enabled

Do send me the place you're working with so that I may diagnose the GUI problem.

I'll create a separate issue for the classic faces.

This works fine in modern studio, unsure why. I'm on V463.
