Can we re-enable achievements after opping someone?

[Diples]

So, I've heard about this website recently and decided to move on to it, since it's one of the best server-hosting websites. But, in order to move the world to this website, I'll have to op myself, but opping disables achievements! Is there any way we could re-enable achievements?

Hi there. If i remember correctly, you should not loose achievements, even after opping yourself!
