Warframe mods loadout changed mid-mission

I wanted to tag this missions but it does not appear in the Tags dropdown list. Apologies in adavnce if I was just blind. 😢 I had tried to search for a similar topic but couldn't find one.

Mission: Railjack, sentient anomaly on Ganalen's Grave

Status: I was the Host, with 1 client joining mid-game

Description (in the order they occured):

• Operator died on the sentient ship, no transference static debuff on warframe when transferred back in
• Warframe lost mod effects (Max HP, power STR, adaptation, etc...) and arcanes did not function
  • https://imgur.com/WSWSvYk shows base stats for wisp
  • https://imgur.com/raD2B10 shows wisp with health mote for total 600hp (300+300)
  • https://imgur.com/fXwPe6T shows the base strength (30), efficiency (50 energy for 2 motes) and duration (30 seconds) for the motes
• Operator became stuck in "sitting" position, like in the transference room on orbiter, as seen in https://imgur.com/Yf7wv4v
  • However, void mode (crouch) appeared to be working fine ignoring damage, even though there was no invisibility effect. https://imgur.com/Q9lDJD4
  • All movement, camera controls, and void dash did not work
  • Attacking (with amp) played the old void beam animation, but stopped after a split second
  • Dying as operator now properly applied transference static debuff to the frame
  • Operator arcanes also lost effect (600ish hp to 100) https://imgur.com/vpbvLDB
  • Using operator in the pilot room on railjack would fall through the ground, and enter archwing when transferred in (no screenshot)
• Sentients started spawning inside the railjack (15,000 m away), really really really unsure if intended

Things that did not fix this:

• Falling off the map to respawn
• Exit ground (Railjack, ground mission, sentient ship etc) to archwing, and back
• /unstuck
• Revived by another player
• Dying, and reviving

What actually happened:

• After mission end when I went to my arsenal and found that the warframe mod configuration had switched itself from Config A to Config B on its own, mid-mission.
  • https://imgur.com/oMqIKIT shows the loadout immediately upon going into arsenal AFTER the mission
  • https://imgur.com/1rNyAOV the loadout I had when ENTERING the mission
• Possible cause might be because the "umbral" one used to be the default "CONFIG B", which I later rearranged to be the first slot, so I renamed "CONFIG A" to B. (I remodded the default A and used that instead in fear of this bug happening again in the last picture.)
• Weapon mods/loadouts were completely normal. Only warframe and operator was affected

ps. I do not have screenshots before the bug happened, and I know my hp was NOT 300, so please don't tell me that I just forgot to set my loadout before the mission started. I ran the secondary objective completely fine before the sentient ship. Oh well.

Replicating the bug:

• Absolutely no idea, as this is the first time it has occured to me.
