Hey!

All the other achievements are present and unlockable, but we're missing 4 achievements linked to the DLC Passenger Flow:

- Tourism Age (Complete 60 levels)
- Urbanization Age (Complete 70 levels)
- Alchemist (Earn 300 stars)
- Astrophysicist (Earn 350 stars)

This is nice - I just put this questions with some other ones on discord (Train Valley 2) and
now one looked into it.
I was informed (3:55 AM) via discord by Sergey Dvoynikov:
"probably a bug, will check".

So if problems show up, it would be better to rise this on Discord server:

For Completeness, the entire message I sent was
(setting the Dev via at [@] to make it better visible - just a hint for others):

Hi, I own Train Valley 1 with DLC and are now considering to buy
Train Valley 2 on GOG to play it on GNU/Linux, too.
When looking around - on GOG forum and here - there are requests/questions
which seems to have never answered (sorry, if I overlooked them).
@Sergey Dvoynikov could someone please answer the following general questions
so I can put the answers to the GOG forum?
1) The level editor seems missing in GOG version - is there a reason for this -
    or is this feature worked on to come soon?
2) It seems existing custom Train Valley 2 content can not be used with
    GOG version - is this just due to the missing level editor?
3) The latest DLC "Myths & Rails" is on Sale on Steam (-10%) but at full price
    on GOG - just a mistake?
4) There is a forum thread (04. Feb. 2022) about 4 missing achievements linked
    to the DLC Passenger Flow: Tourism Age, Urbanization Age, Alchemist,
    Astrophysicist - is this known - and will it be fixed if this is true?
5) Is there any functionality missing when not using GOG Galaxy?
    It was hinted somewhere about achievements - and GOG does not provide
    Galaxy for GNU/Linux.
I would be happy about these points getting clarified and will share the answers on GOG forum
to inform other gamers.
Many thanks in advance for your help.
Best wishes! JMB

1, 2, 5 - there is no steam workshop on gog available, and since
  all the workshop infrastructure is build on top of steam api -
  it is not possible (and won’t be) to use this features on gog.
3 - I believe it’s about shop discount policy, we keep price
  the same everywhere if we able to
4 - probably a bug, will check (edited)

Hello there!

We're working on a fix that will let you unlock missing achievements retroactively, meaning they should unlock for anybody having successfully completed corresponding levels. Please let me know if you have any further questions.

Thank you very much, it worked like a charm!
