RPG Projectile blows up on an invisible part

What is the bug?
When you fire the projectile from the RPG at any row entry/exit, it blows up on an invisible part.

How often does the bug happen? (Everytime/sometimes/rarely)

What steps do you need to take for it to happen? List them in very high detail:
There’s not really any steps, but I’ll list them anyway.

  1. Grab your RPG.
  2. Go to the end of any row.
  3. Try to fire it inside/outside the facility. It will blow up early on what seems to be an invisible part.

Is the bug related to GUI or something that only happens for you? (GUI = the dealership, derby win screen or any other interface)

Something I’ve noticed: I believe the invisible part is the part used to transition the music from inside to outside theme.
