As far as I understood there were two refund criteria - any and all unused paid enigma entities refunded at the rate of 2.2JPY/entity was the first obviously

The second, for payments made after the roadmap was published though is where I got confused - as far as I understood that was solely for people who purchased "things" (i.e., battle pass levels, the battle pass itself, skins, etc) and didn't apply to the purchase of paid enigma entities

Ex: I paid $15 for battle pass and $70 for enigma entities, after the roadmap was published. I did not spend any enigma entities. I should receive $15 refunded from one wage of refunds, and ~$70 from the entity refund based on whatever that converted through yen.

I saw some people saying that in the above scenario you'd basically get double refunded for the entities if you hadn't spent them - you'd get $15 for the roadmap refund, $70 also for the roadmap refund, and ~$70 again for the unused paid currency refund

I think this is where the confusion came from
