collider problem - objects go through objects

[mic3mic4]

I have a collide operator between a cloth (cuda) object and a ground. when I put a force (gravity) to it, some vertices of the cloth go through the ground when they shouldn't. 
The tyflow time set is set to 1/8 frame. the bounce interaction to 0. 
I don't know why that is or how to solve this.
Any suggestions? 
Thank you

Can you post the file?

yes. Attached

You're deactivating particles, but you're not stopping the motion you've applied to them prior. Put a Stop operator in Event_002.

Perfect. It works flawlessly. I was sure deactivation particles basically means stopping their action.
Thank you for the quick response and solution. TyFlow is such an awesome tool.

Glad I could help!

There are some situations where you want to conserve the momentum of particles after deactivating then, so that's why it doesn't stop them by default.
