I think you're referring to this?

OK it's another bug
there are actually two CustomProjectiles
the first shoots strait forward, the second shoots me
I guess the first one is the projectile that target the caster itself, but the target_self: false lead to ignore itself

other projectiles only launched after the first one miss or hit
It's a severe bug

Sounds like you figured it out in the end though? Or no?

I use skip action to skip the first projectile, I think the first one may have targeted the caster, but it can't, so it just fly until miss.
