Hi,
Although I don’t have much good repro info to add, I thought I’d mention that:
a) This is happening for me in 4.10.3, in my GameMode (just a subclass of GameMode, the variables are not inherited and are a mixture of floats, ints and enums)
b) One possible out-of-the-norm thing I did beforehand was cutting and pasting a shared macro from another class into my GameMode (but I haven’t been able to narrow that down as a cause).
c) Coincidently, this has happened to me a couple of times today, and at the same time, I’ve also been running into yet another impossible-to-repro bug where the editor will crash if I try to run PIE without compiling and saving changed classes manually (i.e. letting pie auto-recompile). And that problem I think I fixed by getting rid of a new shared macro I had made that had a “Cast to MyGameInstance” node in it. Shared macros have caused me many hours loss in the past (though I thought that was just when using Structs as params) so I wouldn’t be surprised if it has something to do with them.
The only other possible helpful thing I can mention is that the project was started in either 4.8 or 4.9. Will update if I have anything more concrete…
