Sorry, but the newer NML version of MLSS does not yet have the roundhouses. The old NFO version is on bananas though, and it does have the roundhouses along with some bugs. I didn't upload the new version to bananas yet as I didn't feel it was a suitable replacement yet. Coding is a slow and confusing process for me, so I am not sure how to 'fix' this depot grf, or add parameters. However, as I understand it, the depots will retain the appearance of their build date, and not change once the game enters the next style era. However, converting a 19th century depot to electric in the 1960s might cause it to change to the new style. Unsure.
Thanks for your interest!
Thanks, Supermop! I still like the set even without the roundhouses, I'm interested in seeing
where it develops! I like variety on my routes so I generally have a lot of .grf files going at
one time. (As long as they get along!)
