Make a thread in the mod section, explain your mod (objectives and things like that), show actual progress and then maybe you'll get permission. Just saying you did stuff really does not prove anything I'm afraid.
Next on the line of fixes: moon lord is now always ontop of you no matter how fast you're travelling. It's still an easy fight if you just build a long minecart track and just keep ahead of him all the time while using beetle armor, it's really just a matter of time before you win.
That does not in fact prevent the unintended from happening, fact is there have been much much larger teams of game devs that knew what they were doing, gave release dates they were confident in and STILL had to delay it, sometimes several times.
Be optimistic if you want, just don't be...
