Also what I thought and use the same slider with 4m or 8m intervals that you just adjust. There was no explanation why it was difficult for height adjustment. I can't see it being the sequencer or anything as it should just detect those start and end pieces accordingly.
I mean they could even of had it so you click built the pieces rather than a dynamic drag system if needed.
Yea there are many solutions really. I guess the Flat Ride data structure doesn't support any variable elements, its all static. So if we want variable lengths Frontier might have to change/heavily modify the data structure which means all existing flat rides have to be adjusted as well, which could be difficult but above all takes a lot of time.
