Broken achievement: Multidisciplinary Transport Tycoon

[GeckoDev]

Since the last update, it now states:

Build one of each of the following transport hubs: Underground Metro-Intercity Bus Hub, Bus-Intercity Bus Hub, Train-Metro Hub, Metropolitan Airport, Bus-Metro Hub.

There is no such thing as a Underground Metro-Intercity Bus Hub, and you can not build a regular Metro-Intercity Bus Hub underground... Please, have a look at this.

It should be just an incorrect name in the achievement list as the corresponding building definitely exists. What "underground" refers to is just the fact that the building comes with an underground metro station.

This looks like something that should be reported on the official support & bug forum: https://forum.paradoxplaza.com/forum/threads/how-to-best-report-technical-issues-and-get-help.920608/

I did manage to pop the achievement in 2023, I did have sunset harbour DLC but for some reason it didn't go even with 100k pop and all unlocked (Just the base game in addition to DLC), For some reason once I re-enabled all my other DLC which have achievements tied to them and built all land base transport hub it decided to pop.
I know your post was 3 years ago but for you or anyone else having this issue I though it may help :).
