Hello @dpotuznik and @WolfTechRob,
I noticed this error pops up a lot in UE5, I just started a clean third person shooter project and tried to move the Map asset.
I suspect it might just be a warning message to let you know “hey, I’m gonna break all the reference for this asset into your project settings”.
If you press ok and restart the engine, the stratup map will not show up, even if everything seem to be ok in the project settings menu.
If you refresh those variables, everything seem normal after restarting.
Also. remember to Fix up Redirectors each time you move files around
About your specific case @dpotuznik , I don’t really know what “BP_Explode” is, but if it’s relate to something stored in the .ini files, like these:
It might happen the same, so just press ok and replace those references.
This has been my experience with that error message, I hope this can help you too!
Let me know!
