I've looked into past pages and I could only find the deploying answer for an obstacle. I'm trying to wrap my head around how this works:
If you deploy on an obstacle you don't suffer its effects unless you go to move and your template or final base position overlap the obstacle, then you suffer the effects.
However, if someone flies past you and drops a Rigged Cargo Chute debris obstacle on you, you suffer its effects immediately, before you move? Is this true?
