My entity becomes invincible after a few seconds

[Triphion]

I can't hit the entity's hitbox or even move the entity downwards by breaking blocks underneath him. To top it all of, the whole world freezes, every single entity or game command stops working. This only happens after i've summoned this entity. I think it has something to do with the entity's main coding, but im not sure. Also, after he's spawned, the whole minecraft stops working when i try to go out of the world and save. Also, the texture isn't working. 

 

Here is the entity's coding - https://gist.github.com/triphion/ec368c553b318278b0340b46413e18a8

 

The model and texture java files - https://gist.github.com/triphion/d155c181a0864e1d38e64a9bcd554f2a

 

Also, here is where i register my entities - https://gist.github.com/triphion/536bb17d760f1eebb31f656c608d9dd5

Any sort of help would be much appreciated ^^

Seriously? That's it? Then let me try to set it lower and i'll post the results. ^^

 

EDIT: Thank you so much sir! No more ingame crashes and such, however, the texture isn't working, its popping up as a shadow instead. Any ideas?
