I've noticed that on my team page the Cheese Rule calculator has rolled over to 2021-21, giving me a huge amount of cap space
It would need to be reset to 2020-21
I've noticed that this has happened to me a couple of times, I just sent a cap space offer over to the Islanders. If I remember correctly the error happened before while sending cap. Not sure if the error is easy to correct but maybe this bit of info may be able to help locate it
Makes me iffy on sending cap in the future or would it be better that I have other teams send the offer to me instead.
Maybe it might be worth trying out when there's some free time to mess about with it?
