Game crashing even more now

So since summer I haven't been able to switch mines more than 3 times before the game crashes. Sometimes just 2. But after this latest update it just got worse. Sometimes it crashes randomly when I'm in a mine, it crashes when I finish a mainland mine or start a new one, and half of the time I can't even switch mines 2 times before it crashes. What's going on? I'm not the only one this happens to. It's barely playable anymore and it's just getting worse, with no end in sight.
