Used in Formula for <unknown sheet>
i see this everywhere. i know its from when i delete projects and such, they will leave this leftover trace/breadcrumb ... but why? And does this impact performance? some cells in some sheets have tons of these, so im just wondering why they dont auto remove themselves or how to easily manage those as opposed to clicking every cell of every sheet and then manually clicking to delete link to <unknown sheet> for every occurrence.
