[Bug]: Train flips when carriage attached (related to xussr)

[Sinas128]

Version of OpenTTD

JGRpp 0.58.1

Expected result

xussr has a beautiful system to build consists. With this system you can create consists by manually choosing when the headcar, powercar etc comes

Here is an example of a unit created from headcar, car and another headcar

Actual result

Well not every unit seems to be behave as intented When constructing a multiple unit, the game sometimes flips a headcar with no way of resolving this.

Here is an example of a flipped headcar.

According to George (one of the authors of xussr) this bug does not excist in Openttd 14.0-RC1 But this issue does occur in JGRpp 0.58.1 The DR1A-232 as shown in the image one of the few trains to show this behavior.

Steps to reproduce

1. Take any of these units

D1-376 D1-671 DR1A-232 DR1A-305 and 1,5kv S type electric Multiple unit (Apparently also some electric loco's that are made out of creatable segments but I havent researched which ones yet)

2. Try to create an consist with them

3. The bug should automatically appear

It would be helpful if you could attach a savegame where the consist doesn't match what it is that you expect.

It looks OK here, but this GRF is very complicated and I have no idea if I am operating it correctly.

[JGRennison]

Actually, not to worry, I think I see what you are getting at now

[JGRennison]

Should be fixed now

[Sinas128]

I will attach savegame next time And I should have mentioned that the bug is replicable in any type of new game

sorry :)
