Custom Struct in Blueprint Package Error

Development Programming & Scripting Blueprint

I’m seeing a load of issues with a custom struct when on a packaged build, to do with updating (usually adding to) it.

I’m using a single struct that contains only Slate colours, which I then use across several UI widgets to keep a consistent set of colours.

Adding a new colour into the struct works fine in editor, and will deploy and run cooking on the fly. But trying to do a standalone build produces:

LogClass:Warning: Property ColoursStruct of WIDGETNAME has a struct type mismatch (tag STRUCT_REINST_Str_ScreenColours_0 != prop FallbackStruct) in package: WIDGETNAME.uasset. If that struct got renamed, add an entry to ActiveStructRedirects.
LogClass:Warning: Property ColoursStruct of WIDGETNAME has a struct type mismatch (tag FallbackStruct != prop Str_ScreenColours) in package: FObjectReader. If that struct got renamed, add an entry to ActiveStructRedirects.

The struct hasn’t been renamed, just changed.

It seems that I have to re-compile any blueprints / widgets that reference the struct and save, which I’ve done but still tend to get the errors.

Any help on resolving this consistently would be great.

Keeps happening on 4.14 alas :frowning:

I just fix it by opening the blueprints that used the struct and recompiling and making some Refresh All Nodes. It worked at the end.
Hope it will help…

Find all ref to recompiled, and this error is gone!

This method worked. For me though rather than opening all the blueprints in the reference viewer I opened the blueprint named in the error then had the editor Find References of the specific variable across all blueprints. My reference viewer showed more than 8 blueprints but the Find References for the variable only dug up 3. Compiled only the 3 and the error went away.

This is still an issue in 4.22.3. I have about 2 dozen different structures and it’s a pain to go through and recompile everything any time I want to test a build.
