Assuming you’re using the new MaterialVariant and/or some of the 2022 materials, that hasn’t been enabled for live games yet and will only affect games in studio.
I can’t load into studio at the moment so I can’t confirm if this is a studio-wide bug or an isolated incident but have you tried restarting or reinserting the materials?
That’s strange, on my end I wasn’t able to replicate it for Regular Pattern although it did bug out with Organic. I’m in the process of getting a bug-report sent so if you do get more information with replication steps on your end share it with @Bug-Support . Also try to provide a replication file.
I’ll work on that now, give me a quick moment. It’s going to be hard to lay out steps to replicated as all I did was really load into studio and notice it.
