We're number 1! (Challenge glitch)

[Ghost Land]

When I go to any Nation Challenge page, my world ranking is displayed as "#1 in the world" and so is that of the other person, even when logically neither one of us would be such. I've provided a screen clipping in the spoiler below.

When I look at the championship ladder page, my world ranking shows up as the correct #5. So what could explain the "everyone's #1" shown when I actually try to challenge someone else or am on the challenge home page? Has anyone else had this issue?

Just tried it, I have the same problem.

Can confirm, probably an easy fix, but feels a little nice having a #1 ranking

A lot of new Nations have the same Problem with being firs tin Black Market despite not having any.

This is also related to Nation Challenge so I thought I'd post it here, but Z-day just made me lose two levels. I had been level 65 or 66 continuously for basically the past several months, now I dropped two levels to 63, and I can't figure out which trophies went missing. (Losing my residency trophy is what took me from 66 to 65 a week or so ago, but I still have all the other trophies I had, never ceased to exist, and mysteriously lost two levels.)

The glitch I mentioned in my original post still exists, by the way.

Edit: Just leveled back up to 64 thanks to my zombie population.

Edit2: up to level 67

Edit3: as of a week later, at my correct level of 66
