CGC plugins are fully compatible with YEP so this is more likely a plugin ordering issue if anything. We have tested our plugins with YEP suite for years at this point so there shouldn't be any major issues with them. Once again, please send in your project to the support email (support@myth-atelier.com) so we can assist as it seems that due to some setup issues you are working in an environment that is creating more errors. We are not able to reproduce your errors on our end otherwise and it makes troubleshooting them more difficult.
