This is what I’m talking about, game settings cannot be accessed without saving to ROBLOX. For example, I want to test something in the template using R6, but I need to create a game every time I open the template. If they set the template’s settings to ‘User Choice’, the problem is solved.
I noticed that this issue has nothing to do with avatar settings. The template’s avatar settings are already set to "universeAvatarType":"PlayerChoice" (baseplate api link). Studio is forcing it to R15, and it’s not due to the avatar settings.
This was an intentional change so that template game settings match the default post-publish game settings. I believe the previous behavior only existed on a select few templates and not all of them.
