Train tasks are impossible.

Thanks for starting this thread! I’ve noticed the same issue and wanted to add some context to  what might be triggering this.

I am currently at Mass Train Level 10 and haven't seen a single train-specific task so far. It  seems the issue only starts once the last train type (SC Line) is unlocked. Since we all have to start at Level 1 with this new Pass, the game’s logic fails to account for the fact that the newly unlocked train has no upgrades or extra slots yet. The required quantities are impossible to f' One question for everyone: Does anyone already have one of their older trains at Level 10? I'm about to upgrade one of mine soon and I'm trying to confirm if this is strictly an 'SC Line' unlock bug, or if reaching Level 10 with any train triggers these broken scaling missions."
