Version: 1.0.3 What is the bug: When you are smelting ores in the smeltery, the status bar for each of the ores climbs normally, but when it reaches 100% and should convert to molten metal, it just hangs at the 99% state and never ticks over. After about 5 minutes or so, it finally converts into molten metal but this lag time is puzzling. Mod & Version: Tinkers' Construct Paste.feed-the-beast.com log: Can it be repeated: yes, happens every time with different ores, and oreberries. Known Fix: Walk away from the smeltery and check it again in 5 minutes. It will tick over but only after several minutes of being stuck at 99% on the progress bar.
