Darkmoon overloads RAM

Hi,
I have notice that after I’m opening Darkmoon rewords page, or when I won the fight and rewords are calculated for Darkmoon, the game starts to eat phone RAM up till 1,8 GB!!!
Its clearly some memory leak. Such a static game cannot eat so much!!!

Update.
Issue stayed after Darkmoon. Seams that memory leak related to any new feature quests.
