Hello,

I have made a huge factory to automatize labs, and in doing so have encountered multiple times a bug with U-turn belts.
Since a picture is worth a thousand words, here you go:



As you can see, the U-turn at the top is stuck. The problem is, its totally random. It can work without problem for 30mins, or get stuck after a few minutes only.
Since I used a lot of U-turn in my factory, I was forced to often run all around to gather the materials on the ground and unstuck the belts.
I found a way around by simply making the turns wider, to avoid any possibility of U-turn.

Here another picture of 3 cases where I got the bug, and how I have fixed it:

Hi, thanks for your detailed report.

Could you try if this is still happening in 0.2.7?
If so, could you provide me some save with stucked situation, so I could inspect it more precisely?

Yup, still happening in 0.2.7.
I was lucky and managed to reproduce it a few seconds after remaking a u-turn on a fast belt.

Here's the save: http://www.mediafire.com/?6aa2aek9oia9amq

This should be resolved in the upcoming 0.2.8 release.
