Player disappears when trying to do action

[pspencil]

I was trying to write a mod to make players chop/mine ... while riding on a beefalo. Here is a Github link. https://github.com/Ps-Pencil/WorkOnBeefalo 

As of now, it doesn't have much code. All I did is this.

for k, v in pairs(ACTIONS) do
	v.mount_valid=true
end

This works for picking up things. However, for chopping/mining/digging ..., the player would disappear into the entity it tries to work. When an arrow key is pressed, the player exits from the entity. 

I used "Console Pro" to log the actions and saw that no action is being registered at that moment. 

Anyone know why?
