Just adding this for future reference in case anyone with the same problem finds this post. TheSpaceMan was right (thanks!). The Character was working in the beginning since it starts with the default AIController, but unpossessing it loses the AIController so it stops moving. All I did was reassign the AIController after the possession using the Spawn Default Controller node and now it’s working fine.
Here’s how it looks now: http://puu.sh/cLJy9/8e1ff51b04.jpg
