Its a great feature to mod the weapons but the game os removing them at Will loses the purpose of grinding
I never experienced that on PS5.
On which system do you play on?
Does is happen in singleplayer, multiplayer or both?
In which situations did it happen?
Do you have more than just 1 world and more than just 1 character?
Do you use characters as mules?
Did you ever use any kind of mod?
