Stuck on 89% for researching self cleaning solar panels and it’s not progressed in days. I have multiple packs with max workers and 120% efficiency. Not sure what I’m doing wrong? I’ve tried changing what I’m researching but nothing progresses.
Make sure that the research factories have a research center to deliver to. If for some reason (eg Districts or broken road connections) there is no way for trucks to send the science packs to the research center, then the factories will have full outgoing storage and there won’t be any progress.
