I've been playing with an assembly and adding components. I noticed that a circular pattern that was working fine now does not show the patterned components, and when I click to 'expand' the feature in the tree, the triangle to expand/collapse it disappears. I can edit the part, and have tried reselecting all the components, but this did not resolve the issue. Any thoughts?
I haven't tried this, but suspect it'll work -- deleting and remaking the feature altogether (does that kill any mates/references that might call back to those patterned parts?) -- but if possible I'd like to avoid it/at least discover the cause.
