The unpleasant truth is that a lot of people, probably everyone in fact, has at some point had problems joining a session for one reason or another. This has been made worse recently by the recent problems with the DLS and uploaded content becoming corrupted, TS10 content in Particular. There have even been one or two reports that downloading direct from The DLS (The so called black pages) has caused assets to become corrupted. Even downloading an asset from Content Manager before it actually appears is questionable. Now I,m not saying you should not download direct from the DLS but maybe, as a precaution, you should only download from CM. There is one thing I am certain of however, and that is in order to keep problems to a minimum there should be a universal method for joining/hosting multiplayer sessions starting with buying TS12 and finishing with jumping in a loco without the game crashing! It appears to me that the sensible step is too only download using Content Manager when you can actually see the asset on it. This will at least avoid two areas of contention which is what I meant when I said that.
