[Can't break blocks in Tekkit.]

Tekkit classic? Tekkit Lite? TekkitMain? Tekkit Legends? Sounds like intended behaviour on the modpack's side. Yes, reinstalling deletes your worlds if you don't make a copy of them.

I'm playing on TekkitMain. How do I copy my worlds?

[Can't break blocks in Tekkit.]

Every time I try to break a block with my bare hands or any other tool, I can't break anything. The only time where blocks break is when the tool is used on the block it was meant to be used on. Like a pickaxe to be used on stone and a shovel to be used on dirt.

I'm thinking of reinstalling tekkit but I don't know if I'll lose my worlds if I do so. Is there a fix for this?
