Hey @RRemnar!

I know it can be kind of confusing, but those things are meant to be separated. Here, take a look at the documentation for a rundown on the differences between State, Mode, and Instance.

Where would be best to store the variable that determines if you won that level? So far, I’m using level blueprint to store “global” or level-specific variables but it seems like they’re best stored elsewhere. Game Mode seems to be server-only? So a client can’t access Game Mode vars? I don’t get it.
