For some reason...

For some reason, during the whole day, not a single craft coin fell out, although I played quite a lot.
I see, of course, that the probability of falling out has decreased again.
But for some reason, for example, coal briquettes with a probability of 0.3%, metal billet 0.2%, potions 1%, iron 0.2%, several recipes 0.01% - fell out.
Not a single craft coin (1%)?
