Thought I may as well make a post here to allow OOO to see this more easily.
The Iron serpent gate originally had this setup in stratum 5:

but has changed to what is there currently (the fiend levels ending in Stygian Steed). This happened AFTER the gate became active. Also players have noticed it has alternated more than once.
Second, the Amber phantom gate has rotated in early, and is actually inaccessible by players, thus we only have 3 gates we can enter. As an extension to that, the newest gate on the right - Sapphire Skull - shares the same countdown timer as the Ruby Rook gate next to it, and they both have Vanaduke in stratum 6
Both issues are being discussed here:
