I hope this is not intentional because it is very annoying.

When i try to sell items most times i'm having to right click the items several times before the item gets sold.

When i want to put down the turret i also have to press the hotkey several times before the skill executes. This is not what you want while in combat. Having to stop and look if your turret is there or not. It is very annoying. I have to stand still for a second doing nothing before i can use the turret.

Also sometimes when i want to place the turret it picks it up and i'm stuck for ages standing still waiting for it to stop firing so i can move on. Maybe increase the "hold down the key" timer a bit?
