Looking for an anti-heist adventure module in an art gallery that I found a while back..

Hey all, a while ago I found a high-quality module that took place with the players acting as counter-theft to a Nolzur's marvellous pigments paintbrush-wielding thief. The thief activated paintings to provide challenges to the players before confronting them in a final battle with paint monsters and etc.

​

Does anyone know where I can find that?
