Problem with Humanoid:Move to() on custom creatures/mobs (NOT NPC's)?

Greetings everyone.

I am working on the MMORPG project this winter and spring and I got one problem. I made a goblin with run and idle animation for now. I put a script inside of it, named Animate and put the ID's and idle animation works. But I want my goblin walk around. I made a new script using Humanoid:Move to() and he won't move to specific point I typed inside of brackets. I tried the script on NPC'S and it works. But for custom mobs or creatures it won't work. There are no errors in output... If I just run the game goblin will just stay and play an idle animation. That's my problem for now. I will probably send a lot of questions after I get a good solution to this one.

Edit: The problem is fixed. I just made a mistake. I anchored HumanoidRootPart. Goblin and animations are working excellent now. Thanks to Xeilot and thanks to all who tried to help me!
