优化了游戏离线进度的算法，进游戏不再卡死了。
注意！本次的存档结构有更新，因此游戏中旧存档的离线冒险不会发奖励，这个问题只会触发一次，再次打开游戏就正常了。
Improved the offline progress algorithm. The game shouldn’t freeze on load anymore.
Note: the save format changed in this update, so old saves won’t get offline adventure rewards this time. It only happens once — open the game again and it’ll be back to normal.
