Simulation assert check failed

[flomonster]

What happened?

When adding a specific train schedule the simulation fails with the following message:

  "status": 500,
  "type": "core:assert_error",

What did you expect to happen?

Core shouldn't panic.

How can we reproduce it (as minimally and precisely as possible)?

1. Go to a scenario
2. Import the following train schedule: failing_train_schedule.json
3. Observe the 500 error
