(See the best response by Mightymo.)
Is it intended behavior of null entries in overlays list to cause nothing to show up without any error being output?
Best response
I've just tested this, and adding null to the overlays list does not stop other overlays from showing. Are you certain that you aren't setting the list to null or something?
Adding null to an overlays list won't stop the others from being shown. Setting the list to null, however, will clear it.
