Wrong area level (t16+corruption+irradiated) result in 81 lvl map.

Hi.
I just witnessed a very wierd bug that I never seen before last update.
I entered a boss + irradiated + corrupted map with a corrupted T16 waystone.
The area level is 81, which I believe should be higher.

Could someone please check it? Either irradiation, corruption, or t16 maps aren't working as intended since the last patch.

The map was mire.
Got a screen documentation for everything except placing t16 map, but I am 100% certain that It was t16, 0 doubt.

The map was Mire if that makes a difference.

I don't know if there is a 100% of reproduction, but please look into it, as it is 100% bugged at least sometimes.

It didn't reproduce on second attempt, so sadly there is no 100% reproduction.

More info: Waystone had instilled emotion (guild x1) on it.

Also I did not have double corruption skill on my atlas passive tree.

I think that it is indeed related to mire map.
I just did t15 mire boss + irradiated (from bossing atlas tree) and it is 79lv instead of 80.

I'll record my next mire +level map...
