[2021] Why any trade union items / bonus do not apply to any new DLC production building ?

The new production buildings that came in season 3 are considered multifactories and orchards and not regular production buildings. If an item says it affects production buildings then it will not affect multifactories and orchards because those are categorized as different types. This is not a bug and the developers gave a decent amount of background about why they chose to do this. A lot of it comes down to balancing because they know that a lot of items in the game are really overpowered and wanted to rethink how season 3 production chains could be balanced with items a bit better.
