I am sorry but I will definitely not redo the map just because the Engine is unable to detect the reference on its own. I rather keep the spline and name it to “Engine Related Bug” and make use of it somehow until there is a working solution from Epic.
If World Partition and Android does not go well together, it would mean either there will be a patch for this issue, or we will have the incompability on Android (which i dont think is an option for Epic as well). if world Partition wouldnt be supported for Android, then they lose the crossplatform compabitility (meaning on some platforms it ll work on some it is not available). I think we can expect as Developers the same behaviour between Windows and Android in this specific Issue. If there are no Null Pointer Dereference mentioned on Windows , we should expect same for Android (as Developers) as the Code for Android is generated, we are not written that “for Android” specifically. Thats the general idea of Cross-Platform-Distribution. And if sth isnt supported or not expected to be working on the other platform, Engine should give a Warning or even an Error, as it does e.g. for Materials, Lighting, etc.
