[Splines] Disappearing on edes of level on world compositor map

I’ve placed some splines on to world compositor map, and near the border between two levels this often occurs. Some of the meshes in the spline will disappear and only re-appear when the adjacent level is loaded. Sometimes the meshes on the adjacent level will remain visible even though it is unloaded.

I’m running 4.21.2, any help would be much appreciated. [COLOR=transparent][SIZE=16px]
