As far as I'm aware nearly all of my TSW2 routes and locomotives have now been downloadedand installed in TSW3. However, the in July 2022 released Isle of Wight route with the Class 484 is still nowhere to be seen. Completely shutting down my Steam client and restarting it is not prompting any download of this TSW3 compatable route, which I bought through Steam on July 11th 2022. Why is this DLC not installing? I now no longer trust that all of my bought TSW2 DLC's that should have been installed in TSW3 have actually been installed. I'm now going to have to check every single one! 39 DLC's to check.
There are a few other reports including my own. The other missing DLC (if you own it) is the Class 31. Everything else seems to be there. I have all the DLCs and these are the only 2 I'm still missing.
The only one I'm missing is Train Sim World® 2: Island Line 2022: BR Class 484 EMU Add-On --EDIT-- It just got added now.
Island Line 2022 missing here too (PC, Steam). What's a little worrisome is that the DLC is for sale in Steam - as if Steam doesn't seem to know that I bought it.
Just checked with our Retail team, and it's been 'pushed' now to go live. So it should hopefully start to show in the coming hour or so. Please holler if it's still not there for you in a few hours.
