Compile error with Weaver since 5.3.0f4, not using Weaver..

So I upgraded to Unity 5.3.0f4 and now I can't compile my game because of the following error:

 UNetWeaver error: NetworkBehaviour BaseNetworkBehavior`1 cannot have generic parameters
 UnityEditor.Scripting.Serialization.Weaver:WeaveUnetFromEditor(String, String, String, String, Boolean)

I am not using anything of Weaver, I use Unity Analytics, but that's the only "networking" part in my game. I'm not using any plugins except an InputSimulator plugin, but removing that doesn't fix the issue. Removing Unity Analytics also had no effect. Rebooting had no effect. Reinstalling had no effect. Removing Obj and Libary folders had no effect. I'm drawing a blank here...

I can't find anything about it on google except this issue tracking page

EDIT: I totally forgot... I use Full Inspector plugin, and that one seems to be causing the issue. Will update post when I know more.
