[0.17.79] Crash when loading modded map (TransportLine IntrusiveList corruption)

[ReRetriever]

===============================================
(not sure how to mark as solved, if mods could mark/move this it would be great.)
Solution:

Somehow mini-loader mod was uninstalled/deleted/corrupted(?). the map will not work at all if mini-loader is missing and instead crashes. I have reinstalled miniloader and the map works again. This may be related to another issue since other mods seem to revert when removed.

===============================================

Please see bug below. I can't decipher the attached log. I have attempted to run Factorio as an admin with no success.


What did you do?
- Game starts regularly and works with at least two other maps. linked map below does not work due to attached error log
What happened?
- Game crashes upon loading bar reaching 100%
What did you expect to happen instead? It might be obvious to you, but do it anyway!
- Game did not load as expected.

1. Start Factorio
2. load map
3. game crashes

The log does neither show a crash nor loading of a map.

This is super weird, i can load this save file under 0.17.79 without crash, consistency passes here, but this save file when loading under 0.18.0 without any mods will crash 25% of times, while 75% of times it loads fine. Crash i have is inside "TransportLineManager::update (67)"

Apologies. i uploaded the wrong log. I have updated the original post to show the correct log.

I narrowed this issue down to one mod: "miniloader"

Code: Select all

/c game.player.teleport{-108.5, -154.5}

This save file should work fine as long as miniloader mod is enabled. Fixing this issue may break miniloader.

after re-installing and enabling miniloader mod the map seems to work.

After talking about this internally we decided on a fix. So, I've "fixed" this issue for the next version of the game by restricting loaders to a belt_distance of 0.5 and adding a new loader prototype type (loader-1x1) that has a fixed belt_distance of 0.

This means that mods like miniloader can continue to work but they won't corrupt save file when they get removed. It unfortunately means that if anyone was setting the value to something > 1 it's no longer supported.

As unfortunate as that might be, it was corrupting save files so not corrupting save files being no longer supported isn't really a big deal.

... and adding a new loader prototype type (loader-1x1) ...

Will it be able to filter?

It functions identically to how the loader works now just with a hard-coded distance of a 1x1 loader.
