Ditto. Yesterday while I was working on my project I noticed the same issue of memory loss WHILE working inside it. I had my project open, was working on something completely unrelated to these classes, and everything was working fine in the editor. As soon as I tried opening a standalone game version, the issue was quite apparent that memory had been loss with the classes, and that could only be seen in the editor once it had been restarted. This is really ridiculous. I am not sure if putting these classes into C++ would fix the issues or not, but if it is proven to then I’m willing to go ahead and do so for the integrity of my project, but I’m hesitant considering the amount of work and unsure if it’ll even fix the issue.
's solution where you include the parent classes in the level worked for about 2 months until about 2 days ago.
