Hello. I have recently updated my PocketMine server phar file. I have also downloaded the latest dev version of MyPlot by Jasonwynn10. However, When I try to start my server, I get this. PocketMine is Version 1.7 dev build 1079. PocketMine-MP Crash Dump Fri Jun 1 19:03:02 CDT 2018 Error: Class 'pocketmine\level\generator\biome\Biome' not found File: MyPlot_dev-203.phar/src/MyPlot/Commands Line: 59 Type: E_ERROR THIS CRASH WAS CAUSED BY A PLUGIN
Alpha APIs are changing all the time, so don't expect plugins to work reliably if you are using cutting-edge PMMP builds. I'm sure @jasonwynn10 will update MyPlot with the path change for Biome soon, meanwhile you could check out the relevant changes here and fix it yourself.
