For some reason this mod was able to upgrade trains successfully from tier 1 to tier 2 of the electric trains mod but will not for tiers 2 to 3. Manually sending the trains works but it won't automatically call them anymore. Any ideas?

I tried downloading this mod and upgrading from tier 1 to tier 2, then tier 2 to tier 3. It worked fine. If you post a saved game (perhaps on the discord if you don't have somewhere to put it), then I can try debugging what's happening. Normally if it wasn't working it wouldn't work when you sent them manually either.

One possible workaround might be to try deconstructing and reconstructing the station if it's been there for a while. I'm not sure what the bug might be, but that should reset any bad state it could have gotten into.

your cut/paste suggestion worked. Thank you for your help
