Increased luck after not playing for a while

There was a period of about a month when I didn’t play Generation Zero and when I came back I managed to find a 5 crown version of the Sjöqvist Semi-Auto, Älgstudsare Hunting Rifle and an assault rifle silencer. All in less than a week, I had been looking for these items for a few months.

This raised a question in my mind: is there a system that increases your luck if you don’t play for a while?

Sorry if my English is difficult to understand.

I don’t think so.
But as far as I experienced, they improved the loot system a bit with the last update.

Some bugs where fixes and they introduced some kind of bad-luck-protection. I got some of the 5c DLC weapons I was still missing shortly after that update.
Well, there is still some work to do (hello, 4c AG4).

Just one thing:
If you die often and your adrenaline shots are used faster than your granatgevär can reload, try carrying less of them. I experienced that, if I just carry about 3 of them, I have more luck finding new ones.
