i know for as long as i can remember the auto start feature has been an issue so i run power smelt and the auto start keeps stopping the large furnaces
it also stops the furnace fuel ie the furnaces run with 1 fuel if i manually restart the furnace it wont use that wood 

I will run some tests and see what I can work out.

any progress on this issue

I don't think I ever fully got to the bottom of this one. I'm currently doing a refactor of the code base I'll try and have a look whilst I'm doing that.

Thanks much appreciated.
