I get this exception in the editor when I have the following setup: a panel with a ScrollRect (viewport set to itself, content set to it’s child) and a Mask. It has the TextMesh Pro text as it’s children with Rich Text and Auto Size enabled. Also the Wrapping & Overflow is set to Scroll Rect. After this we start the game and the text is not visible with this exception.

Forgot to add that I’m using the 2017.1.0f3 Unity update and the 1.0.55.2017.1.0b11 TextMesh Pro update.

Can you send me a PM with a link to a Repro of this setup so I can easily reproduce the behavior and error?
