Flickering shadow glitches dependent on camera movement

Hey guys, been working on a map and all of a sudden (without changing anything lighting/rendering/shadow related) my shadows started to really mess up. They looked similar to what happens if you’ve got bad lightmap UV’s, but this 100% is not the case.

I’ve included a before and after screenshot. The light which is being received in this area is from a Sky Light set to Static and a Directional light set to movable, but again, it’s a flickering error so I’m thinking it’s a glitch or something as opposed to something to do with my settings.

These images were taken 5 seconds apart.

Top one is the error, bottom is how it should be

Cheers
