I’ve been expecting the next reward from the current system, just for it to change right when I’m getting it / Will I lose my progress towards the next reward from the current system?

To ensure a smooth transition to the new system, we are making it so all current members will get all the perks from the new system while keeping their progress in the current one until they reach 12 months, which is the maximum level it goes. New members will automatically enter the new system.
