As the new feature of the game has been launched,i have a big question so maybe someone can shed some light on.
There are supports from 1* (50 levels) to 5* (250 levels). As soon as you get a dupe from a higher category, automatically discards the lower one. My question is...
what happen if you spend red iso to level up a 1* support (let´s say for example you level it to 20) and then get a 2* or higher of the same support?
Does that mean that you lose the iso you have invested and start from level 1 at the new star Rank?
As i read in other discussions red iso is not very easy to find and it wouldn't be a good move to level up a support so soon without knowing the answer to my question.
Thanks in advance.
