hello Colby,
it is extremely important how many amperes it is and at what point you notice the short circuit. Start by making friends with your multimeter. It is really a friend of every microelectronics. If the short circuit appears immediately after turning on the voltage, you probably have a shorted PP_Bat line. You have to confirm it. If not, you'll probably find it in a different baseline right after you try to run it (when you turn on the voltage).
-On the other hand, use a multimeter to check the pads under the Tigris IC that you suspect are short-circuited. Enter the measurement result here, I will try to help you interpret it. If it is actually PP_Bat the result will be close to 0.000 and you will look for the short elsewhere. It is also likely that you have a problem with a properly seated chip. It really takes training - it won't come by itself :-) (get a time for it). If I'm right, the measurement in the PP_Bat line will be around 0.300
