Occasionally when using user defined blueprint structs, blueprint nodes that reference them can reference an older version of the struct. This usually requires you to re-create or refresh the node to get the newer version of the struct. A lot of times this isn't a permanent fix, and upon restarting the Editor you may find yourself having to go back into certain blueprints and refresh them.
This plugin automates the refresh process.
The best way to use this plugin is to specifically select and order which blueprints you want to compile in the plugins project settings which can be accessed via it's editor toolbar button. There are right click tools for folders and blueprint assets in the content browser to automatically create these lists in your project settings.
Worth the $2!
Before in 5.5 I was using RefreshAllNodes from github but the owner private it and it crashes in 5.6. Found this plugin and it does the exact same thing but with additional features like making a list of blueprints to refresh instead of refreshing every blueprint.
Overall it gets the job done on refreshing those struct. To the dev, much appreciated!
