thx. If it is ok with you, I would keep bumping this thread. I guess I will also create a new post, because my problem is with a custom plugin and then the editor being in monolithic mode and Hot Reload not working. Thank you anyway for your quick answer
This was one of the hurdles on my path to use UE4 in a way it shouldn’t be. The way I fixed it was to suppy “-modular” to UnrealBuildTool. Right now I did that by adding it to the Makefile, but I’m on Linux. Should I get so far as to make my stuff Windows compatible I’ll update my answer. Also if anyone has a better way than modifying the Makefile that can get randomly overwritten please let me know
