JavaScript coder needed to fix bug in video game

I am in need of a JavaScript coder to fix a bug in my game that is causing the game not to work properly. Whats happening is the bug is causing the players not to be able to fight, hunt, mine or gather resources, place blocks on the map, and it is keeping the player from taking any damage from the monsters when attacked. From my understanding it shouldn't take long to fix and should be pretty simple for someone who knows what they are doing. This job will lead to other jobs if done correctly and professionally.
