I’m not too sure how to describe my problem, so I apologise in advance. I will add in the [pre.com](http://pre.com) volume into my level, I’ll edit it’s dimensions once or twice, and suddenly it stops working… I’ve tried replacing the volume, migrating the map, setting the values back to default, verifying the engine, deleting the “Intermediate, Saved, and Config” folders… I do have a volume encapsulating my whole level… I just don’t know what is going on! It was working perfectly fine until I decided to edit the default values, suddenly it just stops working on this level… ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/6/4/76495ffa907b0e0c7cff1d926746f3f9fad7195c.jpeg) ---

For some odd reason, deleting either the “Build”, or “Binaries” folders fixed this issue…
