Motor controller repair - I noticed this (eek)

I have been given a Q500 that was involved in a "gravitational induced event" (crashed) In the crash a motor was destroyed but the Quad came with a new one and I soldered it up today. However a close inspection of the motor controller has revealed what appears at face value, to be a soldering mistake. The previous owner is not alive so I can not ask him how this came to be. It appears one of the chips has 3 of the pins shorted by a bit of solder. (See picture) I assume this to be a mistake that will need resolution but in the odd chance that this is some kind of a factory modification, I thought I would ask for validation before I buy a solder vacuum and attempt this repair. This is a mistake that needs correcting right ?

 

wow - so this was a factory design ?

I was told by another guy that this was a problem and to remove it...So I used solder wick on that and cleaned it up. so now do I need to bridge them or can I leave it clean ?

 

Thank you for your reply and assistance.
