Just keeping this post here because I couldn’t find any information about this problem. I hope it will help someone to avoid losing a few days like it happened to me.
I was making a rifle, wrote a lot of logic and suddenly it just stopped gripping. For a whole day I went through every node hoping to find what I did wrong but nothing. Later I decided to put the problem aside and experiment in VRExpPluginExample and accidentally added VRGripInterface to the Grippable Actor in Interface, which resulted in the same problem I lost 2 days for. When working with the rifle I wanted to add my own interface which was called similar (VRGripButtons) and accidentally clicked on VRGripInterface. As far as I understand it can not be fixed and I will have to create a new Actor and copy all the logic from “Broken” into it. I will attach a video to the post for more clarity.
