Hello,
I've written to you previously about this bug, and ultimately you believed it was my game somehow being corrupted.
Apart from there being no memory/storage/corruption problems whatsoever with the device I play on, it's just happened on a different device (Sony Xperia phone), with a different account, so evidently game corruption is not the problem.
Not sure why it's caching previous raid results and displaying them incorrectly when raiding a Normal stage 5 times, then saying generic "server returned data error" but it is.
Most often this will happen when you have exactly enough stamina, with it having just ticked over to 40 so you have exactly enough to do the raid. When this happens, the interface removes your raid tickets spent, however next successful raid attempt it goes back up to the correct number.
Thanks
