[Jupiter tileset. Spy mission. Textures are missing on the sentient structure in one of the vaults.]

[Railjack mission alone]

Same here. I can join to other hosts as a crew member, but when i launch a mission from my raijack, nobody joins me. I'm still able to invite my friends to the railjack crew and do missions with them, but can't play with random players as a host.
*Update: it started working properly since this morning

[Why is there no matchmaking for railjack?]

Same. Can join public squads, but unable to host.

[Incorrect mission type on Lich-controlled sectors]

It's been a problem since 26.0.0. Most of the missions are "Exterminate" but they actually aren't. Approximately 30% of the Kuva-Lich-controlled missions are labeled incorrectly.
