Ok thanks Ill be sure to remember this.

Thanks. It was working before so I wouldn't of thought of that. Could you tell from the log or was it just prior knowledge

I recently updated a bunch of mod in a personal mod pack. Before updating everything worked fine but now. I crash every time with a weird error java.lang.IllegalArgumentException: value already present: net.minecraftforge.fluids.Fluid@3c79ad2e I've uninstalled and re-installed the latest 3 or 4 multiple times over and cant seem to get it to work. I haven't found anything on wither bit of the error. Here my log https://gist.github.com/anonymous/f498e4585d9fe4b3fd3b#file-log
