I tried the map for the first time, got a bit more than 2000 trips, but only unlocked the 400 trips achievement.

Is it not possible to unlock multiple achievements in one go?

Version: release-9 (202112131553)

I just finished Wellington with 2081 trips after 10+ failed attempts and the 2000 trips achievement didn't unlock. I'm so angry lol.

Second time I got over 2000 trips. Didn't unlock a new achievement. Guess 1k and 2k trip is bugged.

The same problem 3000+ trip no achievement for 1000 and 2000 :(

Sorry about this, there was a bug in a previous update which caused those two Wellington achievements to not fire. This has been fixed in our latest build, see here for more info: https://store.steampowered.com/news/app/1127500/view/3118177241240831885

Luckily achievements are awarded retroactively so you should get them when you update and launch the game

Thanks for the quick reply and fix.
