SabreCSG doesn't load if a particular asset package is loaded inside a project

[emmecii]

Adding a particular asset package like the Unity Standard Assets, Sabre doesn't load any of his scripts but only the textures of the brushes created and built.

Deleting the Standard Assets folder, Sabre will work fine without any problems, con firming there a conflict bewteen them.

Put SabreCSG in a folder called Plugins, works for some reason
