Hello I have a project that I’ve been working on for 2 years now - I have a massive amount of UMG widgets, this issue runs deep in my project - I’ve spent all morning deleting the widgets that pop up with this issue seeing if its something i can clean out of my project - but I can’t if I delete one widget, it just crashes showing another widget, some I made early in the dev of this project, some more recent
A pattern emerging - It is only the umg widgets that I can multiple instance of at run time, i.e a rows of records like available games in multiplayer, line items of my save games - where I create in a loop using create widget node in blueprint
this only happens on my windows 10 machine while running in the editor, it never happens after I compile the game at runtime in windows or android
I had a bug in my game this morning where I created an infinite loop of map changing which made this issue even more visible (because it would crash out on loading after 3 loops)
I upvoted this thread a while ago while it was a mild annoyance for me - I dont think its a matter of a bad node being in my umg, i think the linker gets confused, this issue I think started popping up around 4.11-4.12 for me
