Need some more help with my custom story!

Way too complicated, just place a sticky area, put the name of the plank into AttachableBodyName and uncheck CanDetach. You may want to play around with the values and add AttachSounds or whatever you want.

Done.

I wanted to say this with method 2.

Your post was lacking an explanation how to do it and when entities collide with a sticky area and CanDetach is deactivated, they don't despawn and spawn a static object, it simply disables the interaction for the specific entity.
