steel oar
(Note: Couldn't find pinned post for guideline, excuse me)
When any shape goes through a Belt Filter/wire-setup (see picture 3), it the shape icon at the end of the belt is gone (see picture 1) - It affects all succeeding shapes containing a part that uses Filter.
This can make it a bit annoying when navigating, since you can use the shape icon as a guide, instead of having to look directly at what the belt contains.
Normal behavior can be seen in picture 2.
