Ringworld Start

This is a version of Aru's Ringworld Start mod edited to work properly with 2. 3 and beyond. The included starting systems are: - Ringworld - Four special habitable sections. Random asteroids and gas giants present in the outer part. - Damaged Ringworld - As above, with two special and two normal ringworld sections; one damaged seam. - Destroyed Ringworld - Single special habitable section, 3 repairable ones. - Super Ringworld - 12 habitable sections (6 normal 6 special). Because 2. 2 declared that ringworlds can't have mining districts, and 2. 3 decided that normal districts were also not permitted on ringworlds, the starting planet is a non-standard ringworld section. You start with the ability to build proto-segments, which are roughly 40% of a real ringworld segment. Once you have Mega Engineering, there's a planetary decision to allow you to convert your starting planet to a normal ringworld section, but be aware that this will cause it to lose any deposits and cannot be done if you currently have any mining/farming/generator proto-segments. This overrides the districts in common/districts/04_ringworld_districts.txt, and is likely to conflict with anything else that changes those.
