Yes I did, there was a bug in 5.5(don’t know if its fixed in 5.5.3) that made uobjects not use a fallback system so it made loading take forever on platforms that used zen storage like ps5. if you had thousands of objects it would just lock up.
Go to this forum, it tells you what line of code in the engine to change.
