It is not unplayable for me or for a growing number of other posters in this thread. So, as @Paul_Bert posts above, is it the users setup, the routes they are using (e.g. <kuid2:214658:101010:1> Aylesbury to London Marylebone as described in my post #51 above), or what (the code included)? A recent update from Microsoft, who have hundreds of programmers, developers and countless beta testers (including all of us) got past all their checks and testing to create havoc for users with a particular SSD controller installed. I experienced similar events when I was managing a large computer network. The reality is that no amount of beta testing will ever pick up all the issues.but for many users it became completely unplayable after the latest update
If you want an example of a Trainz release that was totally unplayable then go back to the initial release of T:ANE. That disaster, despite the claims of some posters here, has never been equalled, not even close, by the releases of TRS19, TRS22 and Trainz Plus and their various SPs.
