Today I realized that while farming common champs on 12-3 I do not get them to level 10 on 1* while using 16 energy as it used to be. I now need 32 energy. 

Upgrading 3 2* Champs to Lvl. 20 on Stage 12-3 Brutal used to cost me 5 super raid Multi-Battles á 16 energy. Now I only get to Lvl. 15 with the same amount of energy. To get to Lvl 20 I now need 10 super raid battles!

WHY DOUBLING THE REQUIRED ENERGY suddently? Or is it just a BUG? 

Thanks for your help
