JohnnyV9999 replied to DottMySaviour's topic in SimCity (2013) Technical Help Q&AWell, probably not a bug per-se, since electronic factories need a lot of educated workers to produce at full capacity (you can easily check by looking if your factories produce at full capacity or not...if not they dont have enough educated workers). It can just be you dont have enough educated workers for electronic factories and for normal factories to increase tech lvl. There is, apparently, another way around that (mind you I havent tried it yet myself)...and that is to build the space center great works, which should, supposedly, increase tech lvl automaticly for connected cities.
JohnnyV9999 replied to DottMySaviour's topic in SimCity (2013) Technical Help Q&ANot sure if this will help you, but I had a similar problem in my electronics city. Electronic factories ate all of my students as workers and due to that none of my industry moved from tech lvl 0. As soon as I removed electronisc factories my tech lvl boomed to max.
