When you fire a shotgun, it first shots all the rounds, and then the sound of the shot plays and the recoil is shown. It's a little weird and very umcofortable

Could you show me a video demonstrating this as I can't recreate it?

Sure.
Look, there's a little delay when I press the shoting button and when the shot sound plays and the recoil feels, the bullets are fired with no delay, but it's kinda weird

Hmm that's very strange, I'll look into it

Mod version?

crafting-dead-core-1.16.5-1.5.0_h1-alpha

What mods do you have installed?

Can you test with only crafting dead?

Still doing that weird firing, look:

here are the only mods:

And it doesn't do that with any other guns?

I haven't tried all of them, but most of the guns don't do that

Can you try with only crafting dead, no other mods at all? I can't reproduce this so I have no idea what's causing it.

I'm gonna try

It's probably optfine's fault. Try disabling the option "Lazy Chunk Loading", worked for me
Thank you, I'm gonna try that too

Any updates on this?
