Borderlands 3 multiple save problems?

Anyone know if there are any major bugs that come with making a second character, like loot loss or problems as such

I’m not new to the game i just want to make sure that the Zane with 20 days worth of play time doesn’t have something wacky happen to it while I start a new fl4k

I just get paranoid about this kind of thing with games and any advice or knowledge on the situation would make me feel much calmer about making a new character (on Xbox one S btw)
Thanks in advance to anyone who helps :v:

I’ve got 8 characters on original XB1 right now, with no problems.
