I wanted to describe better what's going on, but launching with Outer Rim enabled loads with errors:
Failed to load mods: outer-rim/prototype/tech-updates.lua:53: attempt to index global 'tech' (a nil value)
stack traceback:
outer-rim/prototype/tech-updates.lua:53: in main chunk
[C]: in function 'require'
outer-rim/data-updates.lua:5: in main chunk

Mods to be disabled:
• outer-rim (0.4.0)

I can't really describe anything better, sorry.

same

Found the typo, fix out soon.

Does not seem to be entirely patched as of 0.4.3:

Failed to load mods: outer-rim/prototype/technology-infinite.lua:29: attempt to index local 'tech' (a nil value)
stack traceback:

sorry to be repetitive as I have no experience modding Factorio, this exact issue still persists as of 0.8.0 making it impossible to launch the game with the mod:

I'm gonna need a mod list, also this is completely different from the previous which was indeed on me.
I can also upload a version that explicitly crashes with a human readable message, or tell you how to make it. I'd like to know what is happening here.

I think I have a fix for whatever is happening there, and it also looks like planetslib's last release was broken.

Planetslib is now fixed.

I see the update, let me install it real quick and let you know if it's fixed.

If it still doesn't work, I'll launch it standalone and work out the dependency issue.

Update: that seems to have fixed the loading issue :D
Sorry for not supplying much useful information, but that was it. I can load the mod now, and the FTL ship unlocks and Orbital cannon have been modified as intended.

I don't like doing it blind like that, but the info was just enough. :)
