(minor spoilers) Is a kuva siphon supposed to spawn in a syndicate orokin sabotage mission?

[Andrew7811]

I found a rather odd encounter while doing a syndicate mission. Is a kuva siphon supposed to spawn on the other side of the portal in a syndicate Orokin sabotage mission? (The forest Grineer tileset was on the other side)

 

edit: I thought the 19.0.3 kuva siphon changes also affected synicate missions. They were only removed from Invasion and void fissure missions. Still an unusual encounter though

I reread the patch notes. I thought they were removed from syndicate missions as well

Had the same thing happen, but as soon as I entered the mission Lotus commented on the Kuva siphon. By the time I could get through the portal to the siphon it had already harvested 5.

Screenshot Pretty sure the 'Press 5 to use transference' only appears right when you first reach the siphon
