hi @FinestCreative , each string must be placed in the outliner box 7NOYROBLV6F8071CGG3W8U3K9 BZ8B289FOXJD2BI55721IRFZL then the outliner will point to the asset which may have been disallowed see post on how to find this. Quite possibly work the asset after exporting delete and reimport using [Importing Assets in Unreal Editor for Fortnite | Fortnite Documentation | Epic Developer Community](https://dev.epicgames.com/documentation/en-us/fortnite/importing-assets-in-unreal-editor-for-fortnite) If this does not work, read post, [Asset Validation Issues - General / Issues and Bug Reporting - Epic Developer Community Forums](https://forums.unrealengine.com/t/asset-validation-issues/817504/14) otherwise Just wait till epic Support ---

Searhing for the strings in the outliner does not yield any results ---

It seems 40k memory was added due to a few data layers being loaded. Weird this does not show in memory calculation, I am below 80k now. I see less Unkown random strings now but they still appear. So the issue in this post is not fixed ---

The 25k unknown seems to come from verse devices and the props attached to them. And it also seems to contain fortnite devices attached to custom blueprint props ---
