Summary of the problem Storage Drawers Conversion does work with Sulfur Pack Version 1.8.0 What is the bug? I'm getting two types of Sulfur, one from Thermal Foundation and other from NuclearCraft. The Thermal Foundation is from ore processing using Thermal Foundation machine. The NuclearCraft from breaking coal ore from mining using RFTool builder. (Tooltip said from breaking coal ore). First bug is that there more then one. Second bug is that Storage Drawers Conversion doesn't accept ore dustSulfur like Industrial Foregoing Ore Dictionary Converter when converting. So it will not convert between those two. EDIT: Forgot to add that I'm using Conversion Upgrade on the Storage Draw. I'm using Storage Drawers Extras, however this also apply to normal drawers.
