UNO - But it's minecraft v1.0.2

I am writing to report a critical issue with the Uno plugin, which has caused serious data loss and plugin conflicts on my Paper 1.21.4 server. After an extensive and methodical testing process, I have confirmed that Uno is responsible for resetting player inventories on every server restart. This issue only affects players who have interacted with the Uno plugin and is not present when the plugin is uninstalled. I tested this behavior thoroughly by resetting .dat files, ensuring /save-all flush and /stop were issued correctly, and even disabling every other plugin on the server. Once Uno was removed, player data persisted correctly again. This confirms that the plugin is either canceling or failing to trigger necessary save events, which results in total inventory loss — a catastrophic problem on any production server.

Additionally, the plugin's integration with ItemsAdder is incomplete and unstable. The configuration files provided (uno.yml, uno_category.yml) lack required model_id fields, which causes ItemsAdder to load broken textures. Players only see the default black and pink box texture instead of the intended Uno cards. Even after following setup instructions from the plugin's author, including placing files in ItemsAdder/contents/uno/ and using /iareload and /iazip, the models still failed to render correctly in-game. Eventually, I had to manually repair the ItemsAdder files and model IDs myself, only to discover that the Uno gameplay itself remained broken due to missin tesxyes

The Uno plugin has an interesting concept and could be a fun minigame under the right circumstances. However, in its current implementation, it is fundamentally unsafe for servers that value data integrity. I strongly advise against using this plugin until the developer addresses these core issues, including the broken ItemsAdder integration and, most importantly, the inventory-saving bug. I recommend the author add fail-safes to prevent the plugin from enabling unless properly configured, and that comprehensive documentation and verified ItemsAdder files be provided before release. I am forced to leave a negative review on BuiltByBit for now due to the severity of this issue and the lack of actionable support from the developer. I hope these issues are addressed soon, as the plugin has potential if properly implemented.

Great plugin! The UNO system is very well-made, fun, and easy to set up. My players love it and it adds a nice casual mini-game vibe to the server. The code is clean, performance is solid, and the support from the developer was quick and helpful.
Highly recommend if you're looking to add a unique, polished card game experience to your server!
