I was saving for the 7-star crystal in the incursions store so I started to run the new cycle of incursions. After I was done, I realized that I had hit the max(500k) and I had not been gaining any artifacts after the limit. I had no idea the max was 500k and it is stated nowhere in the game. So I reached out to support and they stated they wanted me to spend ~33000 artifacts(the artifacts I lost) before they could refund me my artifacts.
The problem here is that the limit is not stated in-game nor is there any warning when you are about to hit the max. So I shouldn't be forced to spend artifacts when this is none of my fault. If the max was stated in-game, then I wouldn't have hit it. I told support to send me the artifacts through an in-game message but they said they couldn't do that.
