Whenever a smeltery using a fuel input machine with any fuel will cause the server to throw multiple exceptions, now I haven't seen this actually cause any practical issues but it does clog the server log and i just wanted to make sure that you knew about it.

Minecraft Version 1.12.2
Forge Version: 14.23.5.2838
Tinker I/O: 1.12.2-rw2.7.1
Tinker's Construct: 1.12.2-2.12.0.157

Could you provide more information about the Exception? Thanks!

The issue was closed due to no further discussion.

作者您好: 燃料輸入機出現異常
MINECRAFT 1.12.2
tinker_io-1.12.2-rw2.8.3.jar
FORGE-14.23.5.2855
多人伺服端
放入燃料後依舊顯示"缺少固體燃料"
模組本身自帶的固體燃料和原版有的燃料都不行
