Thanks for reporting, this should be fixed in 0.18.2

So i no longer crash, but none of my trains seem to be getting fuel from ammo loader chests. i assume this might be related?

Hm it could be, you have trains enabled in the settings and the relevant research completed right? I'll look and see if I can find any bugs that might be causing trains to be ignored

Yah i doubled checked settings and research. I have both. this is also a world I've updated from 0.17, if that makes any difference

Nah it's probably something I did, I had to change a lot of things for 0.18. I'll see if I can reproduce the error and get a fix uploaded for you. Thanks for letting me know, it really helps out.

thanks man, i appreciate it. If you want a copy of my world, let me know how i can upload it so you can see the issue im having, it should be easy to reproduce tho as none of my trains get fuel. love the mod and glad to see it updated so i can finally update my game :)

Hm I may need a copy of your save, trains seem to be behaving correctly in my test environment. This probably means it's a mod compatibility issue, which I still want to fix if I can.

You can upload a save file using Google drive, Dropbox, OneDrive, or even discord. The save file is located in %AppData%/Factorio/saves. Simply upload that file to Google drive, etc, then get a shareable link and post it here.

If you prefer direct upload via discord let me know and I'll send you my discord id

edit: bad links

It seems the link isn't a public one, it wants you to grant permission for me to download the file

phew sorry, try this one:

Alright I think I fixed the issue, let me know if you run into any more problems after updating
