I didn't check how much sP I had when I tried to get one of the new strains this year through the VIP, and I miscalculated the amount of sP I should've deposited through my currency vault. So it was only after I picked up a strain when I noticed that I now have 0 sP, that I went back and saw that I only had a balance of 23,000 sP instead of the 25,000 sP that is needed to go through with the process. Technically, I should've gotten an error message but nothing happened and it let me buy the strain.
