Just something to add to it.
I think me and @ocenyx had a similar case like this.
We concluded that the cause might be because when you switch your hunter ring near a shrine/pool it gets triggered while you’re in your inventory switching to your hunter ring.
yup happen to me when i swap hunter ring when my toon too close to shrine. whrn it happen i can hear shrines activation sound. and the shrine light become darker.
Not sure how long this bug has been out but i purchased some items for my friend on my device then signed back into my own account but now i cant buy the extra crystals/mythstones storage and i kinda want them,since my warrior is getting a bit full from the items i wanna keep, if you could just let me buy them again on my account or something, that would be great
