Impossible to buy this game in many countries (new currencies)

[BlaXpirit]

This game has no price set for several countries/currencies:
https://steamdb.info/app/334840/#prices
So there is no "Add to Cart" button on the store page and it is impossible to buy the game.

Full list of currencies, linked to official announcements:

• Vietnamese Dong
  
• Ukrainian Hryvnia
  
• Polish Zloty
  
• Argentine Peso
  
• Israeli New Shekel
  
• Kazakhstani Tenge
  
• Kuwaiti Dinar
  
• Qatari Riyal
  
• Costa Rican Colón
  
• Uruguayan Peso

These were added around 15 Nov 2017.

But there was an older set of currencies added on 4 Nov 2015, and even THOSE have not been configured yet.
