I reached out to Tem directly, and he said to look into trigger plate and/or trip wires.
Since I'm almost to Day 70 in this one, I tend to recycle and start over after Day 70, like the content creators. So, I will see how the tripwires work for this setup, and adjust accordingly.
Thanks all for the tips/suggestions! And I started looking thru Hope Radio, couldn't find it and got side-tracked. I'll go directly to Episode 6 as suggested and review.
