Railjack credit drop I'm generally confused how this happens

[civiccabinPrime]

I've played railjack 2 days ago solo on my own and done 1 mission pluto peregrine axis since it's my credit farm is this intentional or did something happen that wasn't supposed to because I'm scared if it could affect my account I got 500,000 credits from doing that railjack mission so I'm just not touching unless it's a mistake because there's no evidence saying how I got it because it didn't show any rewards I got for completion I couldn't view the rewards and it hidden the fact because I was 1.1 now 1.6 i do have boosters but it doesn't affect railjack though and chroma I'm playing currently doesn't have that ability so how does this happen? Because I know you get 125k no more than that for completion I'm mastery rank 18 by the way does this have something to do with it?

Nope completely normal to get hundreds of thousands of credits. I personally do a quick railjack if I don’t want to do The Index.
