使用Lodash。通过Vuex突变更改状态后，删除不会在我的Vue组件中触发反应式重新渲染

我有一个组件，Villager它prop从父组件接收到一个数组。父组件从中拉出该数组this.$store.state。

return this.$store.state.villages.find(value => value.id === 0).villagers

之后我执行一次this.$store.mutation提交以更改给定的数组。如屏幕截图所示，该突变确实有效。但是，我所在的组件没有重新渲染，仍然显示3而不是2。

反应链似乎在某个地方坏了，但我无法确定这个魔鬼。我认为props价值是一种反应机制。如您在屏幕快照中所见，它的值已更改，但DOM并未相应更新。
