um was it intentional to have a specific number to upgrade like for example i have 5000 spirits but the ranking option wont allow me to buy the upgrades that only need 500 points however i can buy the higher ranking skill that cost the exact 5000 i have oh and call me stupid but is there supposed to be a dot besides l and I in the login because i cannot find the dot anywhere to add it.
As far as the upgrades go, you can only select one Per Rank. So only up upgrade for rank 1 and so rank 2 and so forth. You shouldn't be able to buy the last upgrade for 5000 if you haven't gotten a Rank 4 one yet, does it still let you? Cause if it does, that's a bug. Hmm, and here's a screenshot showing you were how to enter the name. It could be "L. Lopez" or without the space and all in caps should work too.
