Ah I see, happens when the alternate rocket part recipes are disabled. Fixed in 0.2.4.

Thanks for the bug report! (´∀`)b

  Started once, no error, then turned on the other installed mods and got this on 0.2.4, and after disconnecting the mods leaving only Galore the same error

I'm attaching a list of mods just in case, I've checked every mod and still won't launch

Fixed in 0.2.5, for real this time.. Turned out the error had something to do with 2 different mod settings, made it hard to debug as it would only crash with a specific setting configuration. (‘’❛ ؂ - „)ᕗ

Anyways, thank you for your time and thank you a lot of the bug report! (´∀`)b

I had the same error, but never once did it start up correctly, and even with only minimal mods enabled, the error still occurred.

space_age_galore/prototypes/vgal-overrides.lua:39: attempt to index field 'vgal-flying-robot-frame-rocket-part' (a nil value)
stack traceback:
space_age_galore/prototypes/vgal-overrides.lua:39: in main chunk
[C]: in function 'require'
space_age_galore/data.lua:1: in main chunk

The mods that were enabled are as follows.
"base",
"elevated-rails",
"quality",
"space-age",
"space_age_galore",
"vanilla_galore_continued"

Postscript.
I was unaware of the update due to not updating the website.
Thank you for fixing it!

Just fixed that in 0.2.5, for real this time. (I already thought I fixed this in 0.2.4 (‘’❛ ؂ - „)ᕗ, sorry)

Thanks for the report nevertheless! (´∀`)b
