When playing with the space mod when launching the first ship you find ALL unichests lose their programming. This is a yikes x10^23. This happens in single or multiplayer and it does not matter where you are headed in the ship.

Great mod though. We have 10 techs left to finish space and FPS is still 60.

When you say first "ship" do you mean rocket, or spaceship? And if spaceship, are you talking about chests on said spaceship, or every chest everywhere in the game?

The space ship. I mean every unichest on every planet is reset the second I hit the "launch" button on the ship control panel. EVERY chest. Possibly Unipipes also, I forgot to check that. This repeats every time I do it. I did not put any unichests on the ship itself. Did you test it with chests and pipes on a space ship? Per above this happens solo or in multiplayer.

Awesome mod. It has made space playable.

If I can help with the debug in any way let me know.

Looking into this, it seems like an issue internal to the Space Exploration mod. The "arcolink storage" is also a type of linked chest, so I believe SE is attempting to do something with arcolinks but it affects unichests as well. I think the fix will ultimately be in the SE mod - I will post a bug report there. I'll also see if I find a way to work around what SE might be doing.

I've verified that the issue is caused by SE - bug filed here: https://github.com/EarendelDevelopers/factorio-mods/issues/304. This is probably also causing other issues you've noticed with setting the item filter. It's an easy fix on their end, so hopefully it gets resolved quickly.

In the meantime, I'll look into workarounds I can do on my end to address the problem, but not sure yet what's possible.

Looks like the next SE release will have a fix. I also think I fixed the crash Arbalezt reported. When the next SE release comes out, please try again and let me know if there are further issues. Glad you're enjoying the mod!

Will do! TY sir!

Meant to add I also added a unichest to the free space ship just to see if that somehow fixed the issue. Nope. But also note Unippipes appear OK. No reset on those as far as I checked.

Given the nature of the bug I would expect unipipes to also stop working any time you launch a spaceship. It's possible there's no visual indication, but I'd guess the fluid no longer flows in or out of the unipipe.

Not sure when the next SE will be released. I realize this bug probably makes the game unplayable, so if you want, you could try this workaround. (Not sure how it'll affect multiplayer, I think you'd both have to follow these steps).
1. Go to your Factorio mods dir (%AppData%\Roaming\Factorio\mods on windows)
2. Unzip space-exploration_0.6.108.zip
3. Edit scripts/linked-container.lua and change line 21 from
if entity.type == "linked-container" then
to
if entity.name == "se-linked-container" then
4. Edit scripts/spaceship.lua and delete lines 638 and 809 that read
linked_container.link_id = 0

Is there an easy way to replace all unichests on a saved game? I think that line fixes the issue but all unichests have to be replaced

By "replace" I assume you mean reset their item filters? There is a selection tool in the shortcut bar which tries to set a proper item filter for every chest in the region selected. It does so by looking at inserters that insert/extract from each chest, and what the crafters or chests near them request/produce/contain.

Yeah I was hoping to keep the filters, sadly that button isn't working well with my saved game
