The tracking skill seems to be broken in EC - the arrow doesn't dynamically track a target, but remains fixed regardless of player or prey location. This is rather serious bug to those who champ regularly and need to find spies. There are also a multitude of inventory bugs where items will disappear from grid view or become overlayed ontop of a single inventory grid. Inventory problems also arise when activating ethereals. I love the EC, the interface is amazing but it definitely is still plagued with a lot of bugs. Really hoping the developers take some time to fix these before they drive players back to the Classic client.
