Hi, so I want to save & load any replays which are made in the game. the replay mode already works, and there are no issues in the editor. but as soon as I try to save or load in the build game, the game crashes at the point I click. does anybody maybe know the reason? thanks!
btw: this is for my game Unity Flight Simulator with over 4.5k downloads, and It would be very nice, if I can implement that save & load function
