I believe the memory calculation only includes the memory 100k limit and not project size as you have shown. 1 is UEFN size limit and the other is the 100k in game limit for devices/meshes ect
I have not seen this before but if its not getting locations check your world streaming and make sure you haven’t mistakenly made the cell super small that’d be my first check. You could also disable world streaming and try it to confirm if it is in fact a world streaming issue.
