[2019] Resource cost of Puerto Rico

Hello. No, we haven't publish her resourse cost anywhere yet. So, if anyone heard about this - it would be just guessing. As @Nevermore135 said, she's just been announced and it's still too early to decide which for which resource she'll be available. When we will be sure - we will post an announcement, most of the time it happens way before release.
