I discovered all my islands and I created katamaran.
So I spent two days (around 10 hours every day in game).
Third day the game started to crash inside different events.
By my oppinion... too much objects in game has and still using incorrect memory management.
Too many using extended memory for that objects.
Programmers not using alocated memory on the others system media (harddrive), which could can catch the increased in game requirements.
Not happen yet.
