The minecraft launcher JVM Arguments are not saving. From what I can tell it affects all versions modded or not. Even if you type new ones and play with them it goes back to the old or what ever it had before. Every time you launch fresh it goes back. I do not know where it saves, but obviously it has the old ones saved because it goes back to those. So the issue is I do not want to keep typing in the jvm arg every time I want to play. I believe it is a launcher problem because I did not have this issue before. I even tried using default arguments but even if you reset it does not save it.
