So we have found that the blueprint system in UE4 to be pretty fragile when you have a game of any size. In that its fairly common to have to hunt down several blueprints and do the old “refresh all nodes” trick to get UE4 to stop tripping on its own shoe laces when trying to package.
[exec] UE4Editor-Cmd: [2017.08.08-18.40.25:845][ 0]LogLinker:Error: BPGC_ARCH_FOR_CDO_[CLASSNAME]l_8 has an inappropriate outermost, it was probably saved with a deprecated outer (file: ...../Projectiles/Base/BP_Projectile.uasset)
Obviously, waiting until the package process errors out is a ■■■■ poor way to find out you have a problem. Especially when doing any kind of auto-packaging/continuous integration.
Is there a way to get UE4 to like “Refresh all Nodes in all blueprints”?
