Codex Not Counting Eximus?

[Frostosti]

I just did the invasion on Phobos Gulliver 5 times for the 3 injectors, i did all 5 runs solo and I encounted at LEAST 3 "arctic eximus" and one 1 "arson eximus" as an ally on the grineer side while fighting corpus.

I scanned all 3 of them, but when i go to codex -> Arid Lancer Eximus -> it shows leech / arctic / arson  with 1/20 ....

how is this possible?

Check Elite Arid Lancers Eximus, Arid Seeker Eximus, and Arid Trooper Eximus. All those units share the same Eximus variants.

i checked it, but nothing wans increased.
After that i did 1 more test.

Arid Hellion 15/20 -> scanned it two times in invasion against corpus -> still 15/20.

It looks like ALL the allies you scan in invasion missions, do NOT count for the codex. But a scan is still wasted and a tiny bit of exp is gained.
