The way I did it was to fly around in RED and look for anything outside of the level. You can also get that error when you place an item inside a brush.
I had found an old post where I had asked that question earlier this year. I had been given permission from RedFrog to redo Rats tactic and I have been working on it for a while trying to fix some flaws that he had made when he first did the original map. Its a work in progress but dont expect it finished anytime soon. LOL

I hope you remember or noticed that he placed ammo for the assault rifle instead of the mini-gun. That annoyed me about that level. I played that level many many times...maybe even a couple hundred times.
