Title says it all, fuel simply will not input into a generator. Forestry fuels (i.e. ethanol) work though.

Probably you have a mod that includes BC 6.0 API in it's jar. If you post your log i can tell you which one it is.

I need the full log (/logs/fml-client-latest.log), upload it to dropbox or some file hosting if it's too big for pastebin.

Looks like my notifications are broken, sorry for the wait.

Here's a pastebin of my modlist:

Here you go

Wait what? According to the log fuel is registered correctly

[13:53:41] [Client thread/INFO] [advgenerators/advgenerators]: Turbine fuels:

[13:53:41] [Client thread/INFO] [advgenerators/advgenerators]: * fuel: 150 MJ/MB

I've just tried the same modlist with new configs and a new world and fuel is working correctly.
