the proven method, as confirmed by a dev as a work around, is to always solve the south pylon first, including these steps :
1. do not touch the north console until the south console is completely solved, each round.
2. Still solve as quickly as possible, so map out the order for the fastest method, the only reason for this is, if you get to the last rounds of adds, on the south side, the two gold mobs, and they die before the north finishes, it will bug out. The console will still be clickable but wont rotate.
My guild has done it this was every week, and had no issue whatsoever.
We tried this tonight after It Locking out about 6 times, and Your method you said Worked First time we tried it. So I suggest people try it at least.
