next patch I will make the grind more easy so is not worth right now and when you load the save the quality will stay at A.
I will probably add the S tier as special events in the future.
thanks for the reply and good luck with updates, your game has a great potential :)
Also, about the crops, do they increase in number, when they have a good quality? (Not x25, but x40-50)
And good to know, it's very valuable information, but I wanted to know the limit of quality, so now I know and I can rest in peace to wait for next patch. Oh and yes, have a good rest, we still need you ^^
