[kovarex] [0.17.14] Temporary train stations while deconstructing rails

[zoolander]

Hi, afters years of playing I found my first bug
I sent a train to my current location and shortly before it arrived, I let my robots deconstruct parts of the rails, then the game crashed.
I was able to reproduce it.
1. Create a temporary station near your current position
2. Wait for the train to be close
3. Let your Robots deconstruct the part of the track, where the temporary station is, while the train is still moving towards it
4. Crash

Hello, I tried to reproduce it several times but I couldn't. Based on the internal logic this should happen, but it obviously happens, so I would like to know how.
Could you please, pretty please, provide a save where you reproduce it, and it crashes some time after loading it?

Hi,
This is how you should be able to reproduce it:
1. You should spawn between two tracks
2. Find the train south of your position. It has four Artillery wagons
3. Send the train to a rail right of your postion

4. Zoom out.
5. Prepare the deconstruction planner to remove parts of the rails

6. Release the mouse button, as soon as the first locomotive is completely inside your construction robot range. So basically when the first artillery wagon is about to enter the green square
7. Game should crash. I tried about ten times and it broke the game in 50% of my tries I would say

I ran into a crash which i believe is for the same reason. MP so no save game, and it was soft-modded, so logs may be quite noisy.
Another player was routing to where I was manually deconstructing rails. My game crashed.

Attached dump and log.

This is, indeed, the same bug.

Thanks for the save file and screenshots to reproduce the problem. It's now fixed for the next version of 0.17.
