My custom C++ object class 'InvItemData' resets to a 'Object' data type after closing and re-opening the editor

[Shaanig03]

My struct variable (object reference) to a custom C++ object class

whenever I close and re-open the editor, the variable’s data type is changed to a object?, this happens not only in the struct but other places like in my function library too

after re-opening UE (struct & function library):

I can change the struct back to my custom c++ object data type however I get a series of errors which doesn’t go away until I delete the’ ‘Item Data’ variable and compile, it fixes the issue and if I undo and compile it works and my item data is restored? O_o

is this a bug? (because of similar topics):

Struct Data Resetting to Default Values on Editor Restart

UPDATE: The bug has been solved! I’ve managed to find a workaround to this bug and thought it’s worth sharing in case someone else runs into the same problem (since I’ve seen couple of posts that go way back regarding this issue). Here is what I did: I set the struct variable to not replicate and saved my project. If yours is not replicating, you may try to set it to replicate instead (for now, you can revert it later). I then closed the Editor. Upon reopening the editor again, I set …

Do you get errors like ‘Blueprint could not be loaded because it derives from an invalid class’

[Shaanig03]

nope no error like that, also should have included the errors

blueprint function lib:

also weird, this time only the blueprint function library throwed a error, b4 I got some errors in my inventory component but now I don’t when I re-opened UE?

now the BFL error is thrown because the function’s input ‘Item Data’ variable data type was changed to object type, so I’m not sure what’s going on , also lemme put my C++ class code here:

is this a c++ project or a BP one with added c++ because i find that to be buggy

also try reloading the class with the bad references in editor, not a good solution but tells you the problem is likely a load order

[Shaanig03]

it’s a BP project with C++ later added

I tried through IDE cleaning the solution, rebuilding it, also by reloading the class do you mean rebuild?, I’m not sure I come from Unity so I’m not that experienced with UE yet

by right clicking my class I’m not seeing a reload option, by editor do u mean the UE editor or the IDE?, srry if I’m being a little stupid xd

[Auran131 (Auran13)]

no for instance reload the BFL

if you’re not too far in i’d recommend restarting with a c++ project. (you can migrate your files)

what i think happens is the BFL loads before the c++ file which causes your class to not be loaded so it defaults to the base class (UObject)

Have you tried deleting the Binaries and Intermediate folders, then opening VS and rebuilding the project?
