I know that there's been some general issues with the interest increasing methods (i.e. the "your extra interest has run out" alert showing up randomly, etc.), but I wonder if this is something new?
I dropped down to 1% interest the other night, which I would assume means that the morty card ran out. I got back up to 2% by collecting my interest just now, but when I tried to use another morty card, I was told I already have that buff, and I stayed at 2% instead of being able to reach the 3% cap.
I know that morty cards weren't expiring the way they were supposed to, but now it seems like mine has expired and now I can't use another one. The extra % in interest isn't a huge deal to me but I just thought I'd point it out in case it was a bug!
