[15.37] Jumping gaps on transport belt

[Mimos]

Hi,

it seems I cannot search the forum for "gap" so I hope this is not a double post.

I got a steel transport belt which is completely compressed but after a tunnel and some curves there suddenly are some gaps. And these gaps are even jumping forth and back.

You can see it jump two times on the horizontal part:
- once the gap jumps forward about one tile and then continues "to be transported" normally
- once the gap jumps forward about one tile and then vanishes (the latter being completely normal if a short stutter occurrs)
Sometimes the gaps also jump backwards.

The savegame. I recompressed it with 7z (lzma2) for a size reduction, so you need to unpack and then zip it before loading.

Is your steel belt one reallllly long belt?

[Mimos]

Yes, it is pretty long (hundrets of tiles, probably more than 1k), propably the longest I got in my factory.

That would be why then There's a recursion limit for how far a belt will update before it stops to avoid a stack-overflow. You just happen to be seeing that point and it causes this small gap in the items because the belts before/after that point are updated in different orders every few ticks.

That's working as intended - to avoid crashing the game we have to deal with these small things from time to time

I'm still surprised that this causes the gaps to occurr and then jump forth or back, but you probably know what you are talking about .
Thanks for the explaination.
