(copy of response from that discussion)
I've been away for a couple of weeks. I'll try look at this in the next couple of days.
The biggest issue is that compat mod just used existing nullius code "temporarily". It has turned into not so temporary, and now there are completing transport drone mods and I have less hope that the nullius team will actually have the time to get to porting/enabling it in nullius itself.
So I'm less convinced that the compat mod is the correct medium term solution. It would probably be better for the nullius compat code to be incorporated into the drones mod itself. Then the person who knows how and why their mod works has full control. I'll see if I can reasonably propose a PR for that later too.
For now I'll take a look at this bug in the next week and update here when I've made some progress
