If I open Studio, search for an instance in the Explorer, then clear the search term, only a handful of instances are visible under each service. The instances that are visible are often also missing children as well. If I start expanding down the tree, eventually the entire service will re-render and all instances under that service will become visible, although there doesn’t seem to be any rhyme or reason to what triggers the re-render.
It’s also worth noting that any directories I’ve already looked into will have all of their children present even after the search. This bug only affects directories that have not been opened yet.
If I search the same term in the same place, I will get the exact same assortment of visible instances. Changing the search term changes the assortment and number of instances.
This happens whether I select the searched instance or not. I thought it might be a case of only populating instances that appeared in the search results at some point (in which case when I search for “shop” anything with S in the name would populate) but there’s an instance named Model visible so that’s probably not the case.
Sorry for piling on with the bug reports I just have a bad habit of breaking everything I touch
