Hi,

You can see the bug on this image, items don't pass this underground belt :

It's easy to reproduce, if you delete the underground belt, or if you change the belt direction, it automaticaly cause a desync.
I switched to solo mod to correct it.
Here is the map :

How was this belt bugged first of all ?
I can't tell you exactly but i marked all the place for deconstruction by mistake.
Then when all drone were removing stuff, i put a new construction plan on the place (at the excat same position) (because i didn't remember how to stop deconstruction), and then (i remembered it) cancel all the deconstruction (maybe 5 minutes after)
That's all i can tell you.

What version of the game is this?
Can you provide steps to recreate the messed up underground belts?

It was with 0.15.37
I tried to reproduce the messed up underground belt without success.
I mean, i know how to cause the underground belt to stop working, but when i change his direction, it doesn't cause desync.
The difference with last time : I'm alone on the server (maybe that ?) and i'm on version 0.15.40.

Here you can see the video (no mods, 0.15.40):

Step 1 : Deconstruction plan
Step 2 : When drones for deconstruction are on their way, rebuild over deconstruction, to send a second wave of drones
Step 3 : Cancel deconstruction plan AFTER one side of underground belt has been removed
Step 4 : Enjoy disconnected undeground belt

Yes, it is most probably fixed for 0.16
