It is downright confusing is what it is, it's like why is this ONE game different, it might be a case of going sideways to get it to work, namely download all the seperate routes I used to make it in the first place to track down the issue.
Good thing I had the old routes CDPs sitting on my hard drive, I did that JUST to wrangle the route for the later games, looks like I have to do the same for TS10 it's just not co-operating with porting it from TC save (as a CDP of course)
Again no idea why this one is having the most issues out of them all, granted it'll help me if TRS22 is all messed up due to how the game has changed if at all, so far it seems they mostly redid the route editor for it, going by videos, the rest just seems like TRS19 w/ a new paint job added ;-)
