Physics 2.0 Collisions: Unreliable for triggering variable changes?

Hello, I have this problem with physics-based collisions:

I get a lot of projectiles ricocheting off when they shouldn’t.

The physical collision happens properly, but a lot of the time it doesn’t trigger the variable change that would make the projectile self-destruct, or sometimes a delay can be clearly seen (the projectile slides off an angled surface and a fraction of a second after sliding off, it self-destructs.

If anybody has any tips that might help with this please tell me, otherwise I’ll have to scrap using physics for projectiles and only using it for destructable environment.

We need to see the related events.
