This article really helped me; six months in to a project, i was close to smashing my pc/monitor/head to bits.
This pointed me to renaming my structures one-by-one until it suddenly started to package. What didn’t help was the error talked about an unknown struct I didn’t even have! There seems to be a problem with Unreal when you refactor which causes this…
Anyway, thanks to this post I am happy again (with just a sore head!)
