Object conversion help

I'm trying to make the bar counter from Lovestruck base game compatible for a friend (for their use only; they're just interested in the bar counter). I edited the mesh a bit by joining two of the meshgroups, changed the cut numbers, cloned barProC4x1 using Create 3D Mesh, imported everything including the rig, slot, and footprint .binary files. I can place it in build mode just fine, objects sit on the surface and barstools snap to it correctly like the original, the only issue is that sims cannot interact with it. They react as if something is blocking their way.

Am I missing something? Is there something else I need to do? I have no idea where to go from here lol. Thanks.
