The last versions of 1.13 and 1.14 changed getInventory#getName because in these latest versions an inventory can have multiple names now, so you have to get the name based off the view, complicated to explain but all I did was change 1 line of code ._.

I also while I was at it added the 1.14 mobs to the hostile/peaceful list. I really wish there was an enum that was sort of made so I didn't have to update this myself, oh well. The mobs added where Cat, Fox, Panda, Pillager, Ravager and Wandering traders
