Modding Help Pickaxe crashing game

the error i get on crash: Client-server connection no longer valid!

Item file:

(yes im trying to make a "mine a freaking planet" pickaxe

Recipe

i can craft it, and its graphics are there etc, its ONLY when i use it it crashes

i tried to find people with the same error but i simply couldnt find anyone getting the same error using google etc or i found some, but they had trouble with multiplayer and some password things,, this is in singleplayer

 

Does the server have the mod installed?

 

well, im trying to play single player... so yes?

 

Ah I didn't see that at the end, have you tried reducing the size first? Maybe like 5?

 

yea still crashes even if its a smaler area that it have to mine... tried with 10, and i think the fishaxe is even mining more than that

 

okay figured the error out, its as simple as if you make it too fast, it simply goes faster than what starbound loads it seems... i reduced it to 8, and could mine, but as soon as the speed of the pickaxe caught up, it crashed.
