I'm getting a strange problem whenever I add a new resource in my game maker projects. It wasn't a big issue before, but now with over hundreds of rooms, objects, sprites, etc., it's becoming more and more annoying. Basically whenever I add a new resource like a sprite or an object, it's like game maker doesn't update all object indexes or something. So whenever I add a new sprite and test the game, suddenly all my objects display the wrong sprites and whenever I add a new object, some instances in the room change. At the start this wasn't a big issue, I just manually reloaded the few sprites and objects I had. Deleting the code and pasting it back for objects did the job. And just reopening sprites and closing them worked nicely. But now doing that can waste hours of development time with how big my resource tree has become. The effects vary from minor inconvenience to an actual pain in the back side. I cant quite point it out, it seems pretty random, all I know is that this happens whenever I create a new resource. Any ideas? If it helps I use the steam version of GMS2 and run all my games on YYC. And yes, as far as I'm aware, all my things are up to date.
