oc_leash stores the length setting as leash_leashlength while oc_particle looks for the setting leash_length
Edit
To replicate the issue you need an item that connects a chain from a distance, longer than 2 meters.
Like a clickable box.
Stand less than 2 meters away and click to se chains appear.
Move away to 4 meters and click, no chains should appear.
Set leash length to 10m and click now the chains should connect but they dont.
