1. Made bloodsuckers more likely on calm, story, slightly more common on intrigue
2. Made intrigue no longer have low threat by default
3. Made abductors have lower weights in general, making them less likely to show up
4. Made sentient disease, revenant less likely on calm
5. Added a new storyteller, "Conversion", which rolls conversion antags.
Malf AI is no longer available as a roundstart ruleset because antag assignment happens before job assignment. On secret, this is not a problem, but on dynamic, there is no way to make malfunctioning AI limited to certain threat levels except by making it a delayed ruleset. Unfortunately, with the upstream changes, delayed rulesets were removed--all roundstart rulesets are delayed, and if it were to roll malf AI, it would simply error, make a runtime stack trace and, in general, shit the bed. There would be no roundstart antag that round, which is *kind of* a problem I'm desperate to fix. So, no more roundstart malf--it's either that or some rounds having no roundstart antags at all.
