[1.1.0] Error loading save: "Transport Line Groups Are Not Consistent"

[UraniumAnchor]

Loaded a save from 1.0, played it for a couple of hours, saved it, tried to load it back up, and got an error: "transport line groups are not consistent".

Broken save is attached.

Interesting. Issue is tripping on the group consistency check, but it is not the primary issue. If you add or change any mods (which makes that save file to load in prototype changed mode) my check for transport line groups consistency is skipped causing other check to fail:

Code: Select all

  13.708 Error BuildCheckResult.cpp:96: Build check failed: 4, cant-build-reason.identical-entity-in-the-way(entity-name.fast-underground-belt), name=fast-underground-belt, type=underground-belt, position={1121.5000000000, -67.5000000000}, setup=true, owned-by-ghost=false, simulation=false.

I think this very well might be related to my other bug report: viewtopic.php?f=7&t=91702 When I noticed this happening I tried to clear them out but it's entirely possible that I missed some and now the save won't load because there's ghosts hiding under real belts.

I have both of these bugs happening to me, in this order, as well.

It is definitely the underground ghost weirdness. I've made a video reproducing the bug, here: https://youtu.be/8O0O1ZNOVeU

Really nice to have reliable reproduction. Indeed the issue is with the ghosts:

By having fast underground belt ghosts on top of real underground belts, when belts are placed on the right, they connect to the ghosts making them not merge transport line group with a group in which underground belts are, however this is a desync state which will not survive saving and loading: after loading, belts on the right will connect to real undergrounds and here the consistency catches: undergrounds on the left belong to other group than belts on the right but they are connected so groups are not consistent.

Think the saves will work after the bug is fixed?

Yes
