1.在某些情况下，萤石不会发光。但当附近方块更新时（如在正上方放置方块），萤石会重新发光。目前为止，本现象只发生在夜晚。

2.在命令方块调试完成后，某些情况下即便在加载区域内，部分命令方块也会失效无法使用，需要将命令方块拆除后重新粘贴指令才能使用（也许是别人将存档压缩后再发给我导入导致的？）

 Direct Translation:
1. In some cases, fluorite will not emit light. But when the nearby block is updated (such as placing a block directly above), the fluorite will re-illuminate. So far, this phenomenon has only occurred at night.

2. After the debugging of the command block is completed, in some cases, even in the loading area, some command blocks will be invalid and cannot be used. You need to remove the command block and re-paste the command to use it (maybe someone else compressed the archive and then sent I imported it?)
