When I have minecraft forge disabled everything functions normal. When it is enabled and I use my enchanted tools, they seemingly "break" blocks more rapidly, except according to the server the block is still there in an invisible state and the block doesnt drop on the ground as loot after destroying it. This isn't a crash or anything of the sort, so I'm not sure what logs, if any, would be helpful. Please help me fix this, as it is rather annoying. As I previously stated, it is only when Minecraft Forge is installed, this is NOT server lag. Thank you. Here's a video I made just as evidence:

Also I should note. This is 1.4.6 and the latest version of minecraft forge on a plain vanilla server.

Tell the server about your enchantment simple as that.

If the server doesn't think you've mined fast enough to break the block then you dont break the block.

Thanks for the quick reply. I'm still a little new to this however; how do I "Tell the server about my enchantment"? The enchantment is only efficiency V and unbreaking III, nothing modded or cracked or whatever. Do I need to add a custom field for this enchant or something regardless?

I wonder how any mod.. tells the server... what to do... on the server...

Simple, just put your damn mod on the server..

Ah I see now, I'll report back as soon as I try this. As I stated earlier I'm literally brand new to this so please excuse my noobish tendencies.

Success. Thanks a bunch man. Merry Christmas!
