Issue description
This happened more than once and I have not been able to fix it. There is molten metal on the molten tracks backed up on the tracks going to metal caster. Metal caster says it is waiting on product as if there's not molten going to the caster. It freezes production. It happened right after building the one for unfinished copper but also happened another time for iron plates. I try deleting everything and rebuilding it but the same problem happens again.
Reproduction steps
Tried to take screenshot or load file but could not figure out how to do either. Maybe I am the problem.
Game version and build number
