Hey there @badreal38! Interesting! It seems the engine is looking for a package that is null. First we need to ascertain what packages they are referencing and then I can likely write a workaround or even find the reference we need to get rid of. Is your Engine build from the Epic Games Launcher or did you build it from source? By “saved the project wrong” what do you mean? Can you explain your steps? Is this error flooding the console constantly?
There’s a couple of possible solutions and workarounds on this thread here but ultimately I’m unsure how a package was generated and failing based on a save alone.
