[solved]101.0&r2302 - Crossing problems after reloading

[z9999]

101.0&r2302

Problem:
After I reloaded a saved game, crossing state may have wrong state, and will cause some problems.
- Cars can't cross the crossing
- When I click on the crossing, simutrans quit without any dialog

What I did.
Saved the game while the citycar was crossing the crossing.

How to reproduce:
- Load the attached savegame
- Click on the crossing

Result:
- Cars can't cross the crossing
- Quit when clicking on the crossing

Note:
Many people reported similar problems.
And a person said crossing status on info window was shown as "(null)" or meaningless strings was shown. I couldn't reproduce this but attached a screenshot.

Assertion failed!
