Thank you so much for replying! At the time before the crashes I was on Vulcan Island in the water near the Pokecenter trying to get the new Horsea that came with the Summer Event. I was there for about an hour ,the Silver server went down for a few minutes and when I came back on I went from around 401k to 209K. My friend who I was playing with was doing the same thing and his money also went down. So I'm not sure if it was a glitch that caused it if you were in that specific area or what. I'm sorry that there's not a lot to go on,but I hope it can help you find the problem so that it won't happen again. :3
