Steps to reproduce:
- Load the attached save with pak128. Make sure freeplay is disabled.
- Fast-forward until the end of the month for "Napik 128 AS" to go bankrupt. This will delete the elevated way under the train, but not the ground tile because it is still occupied
- Try to build an elevated way under the train to replace the deleted one.
Result:
