fix bug

向每一个在旧版本（尚未更新到“联机测试版本”）使用我制作的mod的人，说一声抱歉，我没有注意到你们还在使用，就更新了mod，造成了很多旧存档出现bug。对此我会将mod回退到旧版本，并发布“联机测试版”到另一个mod上。

To everyone who was using the mod I made in the previous version (which had not been updated to the "coop_beta version"), I would like to apologize. I didn't realize that you were still using it, so I updated the mod, which caused many old saves to have bugs. For this, I will roll back the mod to the previous version and release the "coop_beta version" onto another mod.
