How long does a Morty Card last? Is it random? I activated one a couple of days ago after I'd collected my interest for the day and it said I now had 4% but the next day after rollover my interest was back to 3%. I didn't even get to collect 1 day worth of 4%.

The cards are supposed to last for a month, but they're glitched right now and never run out. Bank interest is capped at 3%, which is supposed to include a Morty card but mine was at 3% regardless, long before I activated a card.

Ahh ok, thanks for the info.
