I am not personally experiencing this bug, my wife is for many (around 75%) of sand event levels. We both have iphone XR’s and are operating off the same wifi, network etc and she has restarted her phone.
She had noted the graphical glitches originate in sand empire stages but some of them can persist to other battles. Note the “4” below was generated in sand empire quest but persists in a raid as well as season 3 map level. This was after she reported to me it was a serious issue on a raid so I asked her to recreate it and it only happened for one number but apparently it’s been much worse.
Got worse for me on final 2 stages of advanced. Screen covered in troops, heroes not gaining mana, hits were counting as damage but no special skills to use. I had to use battle items to finish last 2 stages when I really didn’t need to. Shame as I liked the new delay stones would have easily cleared stages without this bug
In the boss stage, the image gets cluttered with the coloured troops and can’t see the board. Can’t carry on playing. I had to restart the game and lost 10 world energy
I also have sand event glitch. It happens after i activate a lamp or X tile not everytime but after the 10th or 11th lamp/X the heroes from that activation freeze as they hit the enemy and from that point on my heroes can not gain mana from tiles activated after the freeze. I can give mana potions to those heroes and they can fire their special that way and other color heroes that do not have their color troops froze on screen act normally until a lamp/x activation grabs that color troop and it freezes those heroes as well.
Thank you for your patience while we dealt with this issue - We believe we now have a fix. Please update your games to the newest version of the game, Version 30.0.2, please note - the fix for this specific issue is V 30.0.1.
Thank you all again and our apologies for this annoying (my words) issue.
