Has Any One seen this in 5.1, in 5.03 our WP was fine but now when we try to load any cells it crashes

I know this is old but ill post a fix here, this normally happens if there is a corrupt texture or cubemap in your project, you will have to go through and open each one until you find the one that crashes the engine.
