Parts list with 1.8 updates:

will it be available on ckan too? We'd like to add this mod to our list so we can use it in our weekly let's play on youtube.

Should get to CKAN assuming Spacedock's add to CKAN option is still working. I don't see it there yet but suspect it will be ok.


And thank you everyone!

Excellent mod, I only have a issue that I got fatal error from B9 Switch

Thanks! Sorry, but I hadn't worked on any configuration or compatibility with B9. It seems to be popular enough to warrant investigating, but this would need to wait until an update is required or worked on unfortunately

Excellent mod, I only have a issue that I got fatal error from B9 Switch and it closes KSP program. I just opened saved craft. If you are interested I can send maybe some logs, etc. to help.

The error B9 throws up would be very useful to see; they're pretty good at explaining what's gone wrong. However as B9 isn't any kind of dependency for this mod, it's likely to be some other add-on that's causing this.

I love it!

Can't wait to see if you do the habitat as well. I don't know why, but I've always liked the look of the Mars Direct habitat.

You can do a pretty decent job of building those using some parts from Stockalike Station Parts Expansion Redux - they have some parts obviously inspired by them, and some nice legs that can be used either with them or with other parts.

Of course, SSPXr requires B9PartSwitch...
