Why does my BSP have a hole in it?
I've tried several different ways of placing the brush and I also spent ages moving the entire map a few thousand squares away on the grid been as it was only on the one side, however the bug persists. The map is symmetrical and the exacts same BSP is on the opposite side perfectly fine whereas on the buggy side, it's invisible in the editor and in play testing. You can also fall through it. I've tried rebuilding, reloading and it is beginning to really frustrate me as I've almost finished the geometry layout and I can't complete it.
Okay. So I managed to solve one side of the map by breaking down my central hall into 6 tiles. That got me thinking and i saved my map then one by one deleted every brush anywhere near the remaining error until it fixed. I finally found that deleting a brush a few hundred squares away made the faulty brush come back to normal and so i reloaded, deleted that same brush again and reproduced it in smaller tiles. Works fine atm although i have only just done it. Hope this helps anyone with the same problem.

Unfortunately, BSPs are known to have issues like this. Especially if there are other BSPs that are intersecting them.
Since this is a floor pieces, can you tell me if it's made of up multiple BSPs or one large one that has been stretched to fit the area?
The reason I ask is, BSPs are known to have more issues when they are larger pieces. Using smaller floor pieces and tiling them will potentially give you better results.
If this does not solve your issue you can always convert the BSP to a static mesh to alleviate some of the issues as Static Meshes are known to not cause issues like this. If you choose this option you'll need to add collision to the mesh in the mesh editor/viewer and generate a lightmap to get rid of that requirement.
If you need, you can post any images of the issue and I may be able to point you in some other directions if these do not solve your issue.
