创世神版本太高
plotme如果检测到创世神会自动调用以便使用一些功能
请降低创世神版本：根据你的地皮版本0.13b判断创世神版本
大概在5.6左右
尝试替换重启

换其他版本就加载不出来，我的端是KC forge1614

这个很多服务器都这样
而且由于0.13b以上版本都是UUID识别的
还不能升级
你可以试试这个插件
屏蔽相关关键词的错误

试试v6版本WE，如果依然不行，建议直接更换服务器核心WordEdit 6.0，亲测结果如下：
Thermos-1.7.10-1614核心可用  KCauldron-1614.201核心可用

补充：地皮PlotMe插件，均为0.16.3版本下测试，无冲突
