I found some rule -
in a small map, all chairlifts are working good.
this map is 253 x 253 sized huge map,
and as shown in this screenshot I roughly made chairlift without saved track,
they are working in half area, and not working half area. (green sign is working, red sign is not working)
and, I tried this- uninstall openrct, and play same map in original rct2.
yeah. all chairlift are working good.
if this save file is not working,
would you mind make a huge scenario map and test?
I really appreciate your attention. thanks!
