Custom escort mission replaces existing ones.
I'm trying to make an additional escort mission. Ship I added is larger, unarmed, but gives +/-10 Reputation instead of +/- 5. Made my own ContractType with just the Escort section, and replaced the prefab list with my own.
Problem is the new ContractType replaces the existing one, so only my Escort Contract appears. If I change the SubtypeId to something unique, the mod no longer works. Not sure if this is a legitimate bug, or just a lack of documentation.
