Need Help Days changes suddenly when I but something at store to my ship

[Valium]

Hello.

Lately, I've noticed that when I go to store and buy something to my ship ( doesn't matter what and how many ), days are going crazy. I mean that when I buy something, it makes there's the next day
suddenly, that's why when I'm trying to but medicines, weapons, bombs and rum, it makes that there's 4 days later immiedately.
That makes that experience of my crew still decreases because everytime I go to shop and but something, there's a few days later at moment...

What is going on?

As you can see here, normally when you at store and you're buying something, there's no something like days' changing.

Now, I show you how it looks in my game like.

There's no matter what I'm buying, it can be even one bullet but after that, there's that information about rum.
Day is still the same but it makes there's less stuff in my ship and crew's experience is worse.
