Go the struct file causing you bother and rename it. These errors usually occur when the struct has been changed but it’s not passed through to everything else. Whenever you change a struct that is being used in other places you MUST play the game in the editor before saving it or exiting. By playing the game it processes all the changes, if you save it and fail to play test the main struct ends up different from everything else everywhere else and you get errors as long as your arm. Renaming the struct in question will do a similar thing to playtesting, it will process the struct and every file it’s associated with and usually fixes errors.
