The bomb squad bugs are surely odd. I have no problems with them and even in the video I uploaded, you can see it working. I never made changes to the Use command for bomb squad techs, neither did I change up the prototype, so I can't think of much else.
Maybe I missed a file or two. I'll upload patches in a separate link.
What happened with the bomb squad officers not coming out? Did they just not spawn? Or are they stuck on the backside of the building?
The foam tender glitch is intentional. You have to move the vehicle at least once using the moveTo command. The script should kick in.
