[kovarex] [0.17.54] Strongly increased belt speed breaks splitter filter

[Anon2k]

Good afternoon, I played with the ultimate belts mod (https://mods.factorio.com/mod/UltimateBelts), but after updating 0.17.52, filtering stopped working correctly for me. I thought the problem was in mod.

However, I turned off all the mods and wrote my local mod, which increases the speed of vanilla belts 4 times (60, 120, 180): https://pastebin.com/1bHP6Vtn



And at a speed of 180 / s, the objects periodically skip past filtering. I assume this happens for any speed above 120 / s.

i will confirm this happens on faster belts and i think it also happens if game speed increased to silly speeds

That makes no sense. No matter the game speed the game updates are still done tick by tick. The game speed actually just adds a sleep between updates to slow the game down.

I tried to reproduce the problem, but it seemed to work well for me (4Xtimes fast express belts).
Could you please provide a save where this is reproduced?

You just have items on the belts too ordered on the sides. Need more chaos

My savegame from the video above: https://drive.google.com/open?id=1VF-Ud ... WVWkZ6DLS9
Just scatter the plastic on the chests on both sides of the conveyor and 100% is reproduced, the steel periodically passes through the plastic filter.

Now you reproduced the bug? Or do you need something else besides video and savegame?

That shouldn't be a fix though, since you're only using half the belt, the problem comes with a mixed belt, which requires a proper fix.

As such, as it currently stands this bug has caused a big mess in my lines.
(I'm not angry about the lines, that's an easy fix thank's to your quick solution I'm just saying it's shouldn't be a permanent solution)

You mean because one side of the belt is all copper and the other all iron instead of them being all mixed?

Thanks for the report, it is now fixed for the next release.

Hooray!
