Really? Been running 10's of missions around my home system over the last few days - have had some Biotech's but loads of Micro-weave Cooling Hoses, Modular Terminals, Neofabric Insulation and even some Telemetry Suites, so I think it may just be the type of systems you are running missions to/from. Around here there are a wide mix of Independent, Fed & Empire systems with boom, none, bust, war etc., High Tech, Agricultural, Industrial & Refineries. Wasn't keeping track of what came from where, but there were plenty to be had and I was being picky about what missions I took.
