Unknown Structure Errors

I am getting errors about unknown structures.
LogProperty:Error: UStructProperty::Serialize Loading: Property… Unknown structure
These structures were recently altered, but everything is saved, complied, and appears to be working correctly. Any suggestions would be helpful. Thanks!

I’m having the same problem. Been browsing through multiple similar posts here on the answer hub but can’t find a solution.

I fixed a similar error by going into each of the named blueprints with this error and refreshing the link to the structure and then saving. It happened to me after I added a field in my structure. I did some work in other BP which had the structure which didn’t show up in my error list(probably since I saved them as I compiled after working on them). I figured you are required to refresh and save all BP that is involved with the structure. When I did this the errors went away for each BP until it was finally all gone and cooked properly. Hope this Helps.
