Extends and overhauls Factorio's burner phase. Use realistic oil and coal processes to create advanced products. Functions as the core and library for the rest of the pY mods.
When making GUI stuff, i usually make it check if the button top left exists, and if not then create it, every time a player joins.
There are even cases where a mod destroys the button and one has no way of getting it back after.
So a check if it is gone to rebuild it is always good. A rejoin can fix such cases then.
