Failed to load mods:
• redrawn-space-compat-fixes
• Dependency AsteroidBelt >= 1.2.7 is not satisfied (active: AsteroidBelt 1.2.6)

1.2.6 is latest on the mod portal

Yup, that is correct, and intentional.

Due to the way AsteroidBelt is currently coded (as of v1.2.6), it is actually impossible to load the game with AsteroidBelt and Redrawn Space Connections, if Interstellar Travel is not also enabled.

Even though there is no inherent incompatibility, it is simply an error command thrown by AsteroidBelt when those two mods are detected without Interstellar Travel. There's nothing else preventing the game from loading except AsteroidBelt itself (as of v1.2.6)

The AsteroidBelt mod author needs to make an update (v1.2.7 or higher) in order to allow the game to load (presumably checking for this mod's existence). See discussion thread on their page for more information.

If you just want to "make it work", then I could upload a temporary modified version of AsteroidBelt v1.2.7 that simply removes those error message restrictions, and allows the game to load, it's what I've been using to test from my end. Attached via Google Drive

That "fix" worked for me, thanks!

Funnily enough, AsteroidBelt ended up releasing v1.2.8 on the mod portal earlier today, lifting the soft restrictions against RDC, Dea Dia, and Metal and Stars mods, that should allow the two mods to load together.

EDIT: v1.2.8 causes circular dependency error on load, since they tried to add an optional dependency to this mod, even though I already have an optional dependency to theirs

Unofficial version of v1.2.9 that should allow the game to load again. Wasn't sure if the mod author made any other changes, so I based this one off of their v.1.2.8, minus the dependency loop, just in case.
