Attached is a mod showing the problem. You can fire the rocket without a problem, but if you mouse-over the rocket ammo it crashes.
It's probably a recursion problem. Adding show_in_tooltip = false doesn't seem to fix it.

Please upload a log as well.

Thanks for the report. The problem is you've defined a recursive trigger effect: projectile A creates smoke B which creates projectile A and it repeats forever if specific conditions aren't met.

I could add in some non-trivial logic in an attempt to detect a trigger effect like this and error at startup but that doesn't make the scenario you're trying to do work.

For now, I'm going to just say: don't make recursive triggers. If it continues to be a problem in the future I'll enforce it doesn't happen.

That's unfortunate, the recursion is intentional and the weapon functions as desired apart from the crash.

Would it be possible to just make the show_in_tooltip=false setting terminate the tooltip recursion so that it does not crash?

I'll look into why that part isn't working (the show in tooltip).
