Im not a dev. so I can’t speak for them, but I’m sure you’ll be asked for a save file. I’m wondering if others have experienced this lately given that I personally have not experienced carrier issues since the full release. Although carriers can be a bit confusing in terms of identifying who is actually a carrier, I have always found that work gets done proportional to my carrier count. In fact you often have more carriers than the number suggests as some workers become temporary carriers when not working as per the video.
Speaking of the video… that’s a really old video and almost of those problems have been addressed. Some weren’t even problems and were just based on Charlie’s misunderstanding of the game mechanics.
Having 7 carriers should be enough to get almost anything done with a community so small so I wonder if maybe something is being missed. Wood vs firewood, priorities that use the wood before they can convert it to firewood...
I haven’t played since the new DLC so maybe this is a new glitch, but with more information I’m sure the community here can help you out in finding a solution.
