Hello!
I'm a 1.7.10 FMUSE server admin. My server upgraded FMUSE version from 1.56 to 1.58, which caused a problem that make players can not enter the server and feedback us with a internal server error. But the game still successly worked on singleplayer mode.

That's curious, since I'm currently running v1.58 on my own server. Do you have a crash report or server/client log that might provide some details?

Thanks for reporting this, looks like it's related to the recent change about food stats reflection @Unknown025.

No prob, will it be fixed soon?

I'm not able to replicate this, do you have any mods installed that might change how hunger works?

No, there's only GVC and Custom NPC.

Okay. I'm guessing you're using a Cauldron/Thermos derivative, does the issue occur if using a normal Forge server?

My server owner said the server is running on Uranium. We haven't tested it on Forge server because of plugin can't work on Forge server.our Uranium server which is based on mixture of mod and plugins(The community around my server is unwelcoming servers without plugins). And since my server are using our country's modder optimized platform. Uranium itself is based on consulting to Thermos, my server have to use this to get our plugin working on.

Yup, that seems to be the issue, as they modify how how FoodStats are handled here. While I don't know exactly what @TheWillyJ was planning with his implementation, I'll rewrite it to not replace the original class.

Thanks, hoping it to be fixed soon.

Fixed with the release of v1.59. Feel free to reopen if the issue is not solved.
