Is there much difference in the experimental versions?

Ahhhh Thank you! That worked . I was beginning to think Id have to wait for an update.

Hey, Im using stable version 0.11.22 and this is the exact message I get.

Cannot execute command. error: [string "game.force.player.manual_speed_modifie..."]:1: LuaForce Doesn't contain key manual_mining speed_modifier.

Hey thanks for responding. Well I tried

/c game.local_player.force.manual_mining_speed_modifier=1000

. And no luck I am playing this game in single player mode. I really don't understand what's going wrong. I have no mods installed either?

So i wanted to speed up the mining rate so I got this command

/c game.player.force.manual_mining_speed_modifier=1000

but it returns - LUA SCRIPT DOESNT CONTAIN KEY -

This worked before what is happening please help?
