So we are now upgraded to 4.10.1 and indeed the PropertyTooltip is now being wrapped properly and not exported.
However two cases are still occurring for us and not wrapped in WITH_EDITORONLY_DATA.
These are in:
- UK2Node_AnimGetter → FText
CachedTitle - FKismetUserDeclaredFunctionMetadata → FText Category
I assume that 4.11 will fix this as there are part of the blueprint system and thus should be caught by that solution.
But wanted to bring this to attention in case others are pulling their hair out
