Is it right to consume 1 Energy point even when walking a path already "walked" by another player?
I entered alliance Quest Map3 and passed for a path already covered by others. I dind't entered in first place and no matter what, it consumed 2 out of 5 energy points

I am at the sentinel node on the right of the map. I walked by a path already covered by the ones before me who took the center. I was supposed to spend 1 energy point to move to the sentinel node but as you can see, It took 2 energy points instead.
I was not the first to enter to the Quest so I have no idea why It took 2 energy points instead of 1.

Is it working as Intended?
