With the new casting table, you can only queue up production of as many glass flasks as there are glass flask molds in the table’s inventory. This is very similar to behavior that was in place in late 2018.
I think the behavior is fine but @Ignasi can please confirm that this is in fact the intended behavior and not some sort of crazy reversion?
Then why don’t we need a hammer to make a sword at the blacksmith bench or a saw to make shaped wood? I don’t mind putting molds into furnaces as a way to get around without this station. Or may be having an ingame saw tool to make shaped wood from my inventory, without carpenters bench
But putting molds into specialized station dedicated entirely to casting is just plain dumb.
