Mod on Discord - "canadream_toll_patch.scs" - doesn't solve all the problems with the gates.
I made my own and the gates all work ( in Mexico, USA, Canada).
Check both mods, they're not closed.
"Midwest Expansion" does not contain a file: "tollgate.sii" At least version 0.154free.
My patch from the post 257 viewtopic.php?p=1394677#p1394677 should be above "CanaDream_v2.11"
Other map mods above should not contain the file "tollgate.sii".
It is worth checking it yourself: \unit\hookup\tollgate.sii
Im sorry for the translation errors, but I don't speak English.
