Minecart tracks do not have proper facing, either N/S nor E/W

Please force a crash by pressing F3 + C for 10 seconds while ingame and attach the crash report here.

I could not force a crash log by f3+c for 10 seconds. Not even after 20 seconds.

But I did play around with it some more, to make sure it would repeat.

When the

Har, spoke too soon. As soon as I went back to the game, and got out of the F3 screen, then it crashed 🙂.

When the east/west tracks appear to face the wrong way, it is rendering – just changing the view distance to force the game to redraw makes it look right.

I cannot find the "attach file" button.

However, it is relatively short (more stuff – important – below the crash):

If it is just rendering – note that I am actually playing single player this time, I normally play on servers – then the immediate "to check" is optifine. I'll disable the forge stuff as well – it's primarily for NEI, but also for dynamic lights (handheld torches), and lloverlay (displays the light levels on the ground – turned off in that video).

And, retesting with optifine removed – the east/west tracks are now showing up properly. And, they clearly place down – and draw – north/south, and then turn and redraw east/west.

But the north/south powered rails that decide to change facing, break their existing connections, and go east/west – that is still happening.

The force crash occurs after you release F3+C, not right after 10 seconds.
