在太空探索中，每次保存后高速公路就会被删除？

更新加载别的MOD，只要有改动，就存档就被删除高速公路？

I am sorry -- the 2.* transport drones mods contain regressions. I have submitted patches, but they have not been incorporated. I can not fix this problem because it is almost certainly due to regressions within the transport drone mod you're using with my mod. The only solution would be for me to make my own fork of the transport drones mod and maintain it, but I don't have the time for that sadly.

可以正常回归

You can test my mod out against that -- you will need to edit the info.json to switch the dependency over to that drones mod. When I last tested it, that mod crashed. But it may have been improved since then.
