【BUG report】The game is stuck after defeating Mueller in the second fight

[zdream]

1. Defeat Mueller in the second fight
2. Select: Take Mueller back to the ship by my self
3. Leave Mueller in the BOSS battle room alone,
4. Return to the ship first
5. Try to go back to "BOSS battle room" (The game will get stuck halfway)

【BUG 报告】如果第二次打败 Mueller 之后可能触发卡机

以下是复现步骤：
1. 第二次打败 Mueller （这个是有成就的）
2. 选择自己把 Mueller 搬回飞船
3. 然后先把 Mueller 留在 BOSS 场地
4. 先回飞船（然后游戏提示要把 Mueller 搬来）
5. 尝试回 BOSS 场地搬 Mueller，但是半路会卡住，游戏死机。

猜测是地图加载问题
