All those stuff will be fixed in the end.
But its no so easy to do as there is the real life and people have to work.
And not everyone from our staff team knows how to work with java or whatever you need to know to fix bugs and error.
un-enchanting was taken away cus people were abusing the bug with the meteor mod equipment.
the dungeons are generating but for some reason our lead admin decided to half the spawn rate of them and make them more rare.(or to reduce lag maybe, really no idea)
the modpack is broken atm(unless they make some new patches) and fixing the modpack for someone else is kinda hard.
Also all the other big servers you see, I guess they might have much better hosts aswell and maybe thats why some of the crash causing stuff are still there.
