Freeware C36-7i Is Very Confusing

So I recently got back re-downloading the old C36-7i, and I installed the B&O patch from the library.
Now here's where some people get confused. The engine shows up in the world editor, but once you save and return to the scenario, it dissapears.
I've been dying to get this engine to work, but just can't figure out how to fix this.
Any help is appreciated!
