[19:43:16 WARN]: Can't keep up! Is the server overloaded? Running 7318ms or 146 ticks behind

This is a amazing plugin!! Thanks you!!
I have a suggestion, would You add custom model data for each item inside gui?

Its good but it wont give me the diamond, can someone help - i havent changed the base command

Great plugin! Simple and works perfectly!
Recommended than the premium on Christmas+ :D

Ставлю 4 звезды из-за непонятности настройки в плане дней... Всего 24? Если больше, то исправлю на 5.. Объясните просто как это сделать, мне нужно сделать 31 день...

Awesome plugin! InventoryClick error bug with Sounds but I don't really use sounds so that is fine. But awesome plugin, deserves 5 stars 100%

Awesome idea, really like it! Please consider implementing a way to give the christmascalendar to players on join, because I have many players and cannot give every single one a christmascalendar.

Works great. That's what I've needed for my server. Even solved my problem with "UseOlderDays". Thank you!

Just with some easy to cope-with Problems in the beginning - this piece of fun does exactly as described.
Easy to configure and use.
A great way to bring xmas feeling onto your server!
Thank you.

Please new update:
Open Gui menu with command: /calendar
Can open menu without only December
Can take rewards only December.

very good this plugin I recommend to everyone to make players happy at Christmas

This plugin is really easy to use, features and performance are very good, is a good choice, I hope to develop a good plugin.

Good Job! Nice author great plugin!!! thanks for plugin. 1.13 supported plugin? thanks
