Hey! I just fixed some bugs in GUI and it has to work correctly now!
I also have added predefined-commands feature which means that you can predefine commands for new Easter Eggs in config! So you don't have to to add these commands every time you make a new Egg!
If you want to use the feature, please add these lines into your config.yml!
Code (Text):
predefinedcommands: ## Variables: %player%
- "give %player% stone 1"
