Side note:
i have AAI, Space Exploration and Krastorio 2 as active mods
also i am using only the splinter version of Underground + Subways and only Underground + Subways is active from the mod mash mods

Thanks, i'll have a look. Is it always happening or just odd occasions

Still happens gonna try disabling the other mods

It works on its own so i'm guessing it's a compatibility thing.
Should i list all the mods i use or should i just not bother you with my stupidity? :D
(mabe it's the fuel i used... or the other mods add something to trains that makes them brake when you enter a subway. I don't know)
Update:
it's from the other mods (trains consume fuel faster and stop slower) i am just guesing

Ill put a check around the grid and have a look at anything else thar may be nil

I am getting the same error while using other mods. Rest of it works just not the subway stops.

possible fix, using mobile so not downloading other mods to test

Sorry but after being off line I have decided to no longer work on this project. see message on info page hopefully somebody else takes ownership.
