"Space platform" research requires to send space platform starter pack to space.

I noticed that some mods can affect random (i thought they not if they do not add any items)
Mods list:
even-distibuton: 2.0.2
flib: 0.16.3
factoryplanner: 2.0.20
StatsGui: 1.6.1
StatsGui-HandcraftTimer: 0.2.0
blueprint-sandboxes: 3.0.3

Blueprint sandboxes I believes adds some things I think, though they're hidden by default; I forget exactly what they are, but since the randomizer analyzes the whole game to see if you can complete it rather than just the items, even very small tweaks can mess things up in that way.

Also, by space platform starter pack, do you mean the recipe, or ability to send it?

Ok, i see, blueprint sandboxes modifies loaders and other godmode items.

By space platform starter pack i mean recipe.

Okay, I think this is done by item randomization, which does not currently account for the fact that the starter pack is used in a "special" manner. Thank you for letting me know; I'll fix it in the next version but not sure when that'll be done. In the meantime, I would cheat yourself in a single starter pack so that you can progress. Let me know if you need any help with how to do that.

Got the same problem, with a different seed:

Thanks! I'll look into this the next time I work on the mod; in the meantime cheating yourself in a a space platform starter pack might be good. I thought I had fixed it, sorry.

Thanks for your effort! Yes, i cheated myself one starter pack.

I guess recipes will break / change if i update from 0.3.8 to 0.3.10?

Yes, they will all break. I would not recommend updating unless you wish to restart.

Also, I think I fixed the bug this time in the recent version at least, but we'll see.
