What happens when you start the Windows PoolMath a second time? I noticed that it takes two starts with all logs until the Windows PoolMath is properly synced. I actually wanted to report that as a potential bug, but forgot about it again, not using the Windows version very often. The logs itself show straight away, but it takes a second start until the new values show on the main overview page.
OK. I started it up again, and this time it worked. But it did this twice before. Once telling me I was 7 days behind (yesterday) and now telling me I'm one day behind. Only happened on the Windows App.
