There were over 170 guides listed in Train Simulator Classic Community Guides for as of last week for. The majority of them have disappeared. Steam has no definite cause and may be an issue with DTG. Can you please look into this? These guides are invaluable especially for newer players. Could it be something when the name was changed? Please do not let this degrade into a finger pointing issue! Reply from Steam Support: "Hello, Unfortunately, Steam Support doesn't have any information on what happened to those guides. There are many factors that could be causing guides to not appear for example, the creators not accepting the latest Steam Subscriber Agreement to the game's publisher updating what content can be posted in their community hub. It could also be a temporary issue with the Steam Servers loading that community content. I don't have any further information regarding this but if you have any other help requests that we can assist you with, please let us know." Steam Support / Jr. Portal Cake Tester Vido
It shows 140 guides. They are from Steam Community members. I doubt that DTG has anything to do with this - or were the guides you are missing published by DTG?
