As some of you may have also learned the hard way, I managed to produce a board where VCC goes to pin 83 and GND goes to pin 84. (VCC pins are 3, 13, 23, 33, 43, 53, 63, 73, 84, 93, GND pins are 4, 14, 24, 34, 44, 54, 64, 74, 83, 94)

 

Does the chip function 100% with that pair of pins cut?

This topic has a solution.

All Vcc and Gnd pins should be connected. Run wires to the pads to connect them.

Yup. I fear you're going to have to cut and wire each one. Alas.
