Heat Map Isn't Working

Hi folks, I rearranged my defense the other day so I didn’t have any heat map data for a while. I got attacked for the first time today, -25 trophies, no gems. I checked out the map and exited the game. Next time I logged in, I had +9 gems and -3 trophies. I checked out the heat map, saw that it had changed, checked out where the invocations were used, and exited again. I log back in a 3rd time, -25 trophies, no gems, and no invocation circles on my map. Isn’t the heat map supposed to be an aggregate of the past 24 hours? 

And now an hour later I don’t have a heat map at all. I haven’t changed my defense. It’s pretty broken.
