Yeah, this has become a must-have for any playthroughs i do - And so far i've been busy setting up the infrastructure on the different planetary bodies to support my launchpad colonies.
Did a quick check in the log, and of course its a 'NRE', likely brought on by changes to the vehicle loading code from the latest patch...
Here's hoping that this can be solved with a minor quick-fix applied to the current release-branch, but you never know...
I've tried downloading the source before but could never get makefile to work properly with windows, otherwise i'd be inclined to take a look myself
In any case - Know that we're waiting patiently @taniwha and look forward to any news from you regarding development!
