Coins Missing

About two or three weeks ago, I noticed a drastic change in my coin collection. In Might of Helios I had around 75k coins one day, and suddenly I ended up with 15k. At first I thought I had recruited Smoulder from the reputation upgrades, but then I checked and realized I hadn't done so. It also happened in Wisdom of Odysseus, but I had around 60k one day and 15k another day. I have gathered up almost the same amount of coins I had before, but I thought I should make a post just in case this happened to anyone else. What should I do now? and Has anyone else had this issue?

Yes, Been happening to me also, they just disappear. 10M here 12M there. Just started this week.
