Major problem upon closing the editor

So i had the editor open working on the project. Decide to make backup. Close the editor do backup. Open the editor, at 93% get this. I delete SG_PlayerItemsInBp (the last class reported with error) project opens and many links are broken of which only some are reported. The rest i have to run the entire game to find out EVENTUALLY about them. Fix the project after 20-30 mins (at this point i have done this more than 5-7 times so i almost remeber where everythin has broken down). Close the project, open project… guess what…

I GET THIS!!! AGAIN!!!

What do i do? (i am very disappointed at this point)

It appears to have to do with the structs on the Tmap in the SG_PlayerItemsInBp… In short Tmaps with Structs that contain structs causes problems… Probably not for sure. I tried to reproduce on a new project. Crashed first time but then it loaded normally. So i guess when initializing default structs things can go bad. Maybe it has to do with the order structs are initialized (when laoding the project). Say struct A contains Struct B If A gets Initialized before B then crash?? maybe dunno really.
