Hello everyone,

Today once I started fooling around with the trains (Driving them into a loop) I spotted the following bug:

I made a loop with 12 curved rails drove a long train (3 trains + 7 cargo wagons) into it and started to loop it (w + a).
After some time one of my other trains also entered the block.

This is weird because my train should block the whole circle (even if it's divided into 4 pieces).

So my question is: How can the signals in the loop be green?

Your signals are where two curves meet not on the one straight rail in between.
That might be the cause but i'm not sure. Try resignalingthe signals on the straights between to curves, meaning on the diagonals not where they are now.

Actually, it looks little bit strange, could you provide the savegame?

Since the savegame is around 13 MB, I remade the bug in another (smaller world).

To activate the bug:
Drive with W+A (to force the train into the loop) and loop the train at least 2/3 times.
After 2 loops the bug will activates itself.

I tested this bug again in 0.12 and it's still there.

Is there any update yet?

If you can edit the topic name you might change the game version number up to the latest you've been able to reproduce the bug.

Thank you for reporting, this has been fixed for the next release.
