To fix the very little minor bug, open up the route file with
Notepad or Notepad++, see this code?
;RANDOMISATION COMMANDS
;TRAIN
With Train,
;$Sub(10) = C151
;$Sub(11) = C651
;$Sub(12) = C751B
;$Sub(13) = C151
;Train.Folder
$Sub($Rnd(10;13)),
Train.Folder
C751B,
Change it to,
;RANDOMISATION COMMANDS
;TRAIN
With Train,
;$Sub(10) = C151
;$Sub(11) = C651
;$Sub(12) = C751B
;$Sub(13) = C151
;Train.Folder
$Sub($Rnd(10;13)),
Train.Folder
C151,
Fixed! (Please change the one in bold, do it yourselves!
Apparently you are lazy by copy-pasting.)
