Random Collision that I cannot remove! Help

I have been working on a temple like environment using the infinity blade assets from the marketplace. It has been coming along nicely until I started testing the environment for issues in game etc. I noticed there are some areas where there is collision. However, it isn’t collision from a mesh or blocking volume, its just randomly there in the shape of a rectangular cube.

I have not seen this before, there is no bsp, no blocking volumes etc. Just static meshes.alt text

I managed to fix this issue.

If you were able to resolve the issue, please post how you did so, so that other users having the same issue can use this post for reference.

Thanks!

Collision issue with inefficient mesh. The collision had to be recreated.
