Bug Description

I just downloaded the modpack yesterday and I found that I have issues with left-clicking actions. For example, I cannot punch any mobs. I can break things that can be broken instantly and if I start breaking a block that cannot be broken instantly, then stop breaking the block, the little cracks in the block remain until I try to break another block.

Did this behavior use to work in the previous version?

I don't know. I have tried previous versions and have encountered the same issue.

Steps to Reproduce (for bugs)

1. download modpack
2. open game
3. can't punch things.
