When using BETA 3.4 (Build 91) on Windows 10 I'm getting the error Error code: (utils.js.19) when setting the reset pose. I'm able to refresh the scene and keep working and sometimes the reset pose works without the error. CH is on a local drive and the puppet I'm using I use quite often. I was getting some other error messages but figured out those were related to some virus scanning software I recently loaded on my computer.

Also getting this error. "Error: triangle side lengths must be greater than or equal to zero. Error code: (utils.js:19)". Not sure what any of that means (I'm new to CA), but it makes it so I can't see parts of my character in the scene preview, and the behaviors on what is still visible don't function.
