I am on level 381 on Bubble Witch Saga 3 and have been playing for 3 years and this has never happened before. A few months ago, I noticed my Stardust count went down randomly, without me purchasing anything. I assumed it as a mistake and moved on. Fast forward to today and cumulatively, I've lost around 1800 stardust. I haven't spent any of the stardust nor have I made any progression with Stella's house. I play on iOS 11.2.1 and my game is updated to the latest patch. Help with this dilemma would be greatly appreciated. Thank you in advance!
