Getting in Mech during mission zeros my credits

Same here, really disappointed as I really wanted that Dominate ability.

There seems to be some fundamental problem with Leviathan.

I have not even gotten to the mech, and both my credit and medigel count got reset. I am currently on the Reaper attack / getting to Ann Bryson phase of the Namakli: Leviathan quest, on Xbox Series X. This needs to be fixed asap, ME3 economy is scuffed as it is, no need to also reset our progress...

I have a save file right before getting to the planet with 63 025 credits and 8 medigel bundles. If I land, it is still displayed correctly, I don't know yet what causes the reset, I'll try to investigate.

Edit: I just got instakilled on a ladder by a random Harvester bombardment again (honestly, who the hell thought this mechanic is a good idea?), but I still have my credits - so death is not the cause of the bug, or at least not every time.

It might be quitting the game mid-quest, since I started this yesterday and only today got back to it, in that save file, my credits are at zero. I'll test this theory later with a reload, but I want to complete it first, I'll go mad if I have to go through this section from the beginning again.

Edit #2: I can't reproduce the bug. After finishing the mission, I went back to my pre-mission Normandy save, landed on the planet, and restarted my xbox. Reloading the Namakli save did not result in losing my credits and medigel... Sorry, no other idea comes to mind, my manual save file, the "Restart Mission" save file, and the autosave at the landing site all worked without an issue.

for me, i get zeroed when getting in mech and killing the wave. 
i have tried where get into mech and kill brutes and get put of the mech to killthe rest. The credit disappears when getting back into mech to take it to Cortez. 
so its gotta be mech glitch. I tried repairing files but no resolve.

Two years later and its still happening...
