I’ve had this bug for a few months now, but it just became worse, because not only items that come from bundles are always first/on top, but most of the times the inventory isn’t even loading
(and sometimes can’t even go past the 3rd page of items!!!)
I’ve noticed this bug only happens with bundles once Roblox updates them (eg. converting from norma/static heads & faces to the weird dynamic faces).
Items page needs to get fixed soon, as many UGC creators including myself, use the inventory page to check our last uploaded item to go and configure it once it’s up.
