Late game is unplayably buggy:
1. Peons definitely get stuck at drop site/catapult (within a few seconds), if speed is upgraded;
2. Peons randomly permanently freezes (throw them does not help);
3. Peons definitely jump into hole at respawn (within a few minutes) (throw them does help);
4. Earthquake freezes for dozens of seconds;
5. Ballon does not respawn after building detroyed by stability;
6. High level building upgrades never pay back because stability drops way too fast;
