This is happening every few months and I end up wasting my limited free time trying to get it to accept the unchanged resource pack when I haven't made any changes to any of my mods. Nothing has changed! I used it yesterday without any problems and the day before and the day before so why is it suddenly not accepting it. Why would it be something to do with my mods? I haven't made any changes to any mods! The only thing that changes is that I have to download(?) the minecraft launcher every time I start my game.
Is there a way to set it to offline only so when I find a launcher that doesn't create problems I can just keep using that one?
Well 2 1/2 hours later it suddenly decides that my resource pack is perfectly fine - too bad I don't have time to play now.
