Train fuel tab inaccessible when train drives away (MR)

[zobros]

If you open the train's interface from the map, the contents of its fuel slots will be visible. However, if you do this directly (not from the map) and the train leaves, the fuel tab will become unavailable.

Not a Bug. This is how entity GUIs work. They don't let you interact with inventories when out of manual manipulation range. Same as how chest GUIs close when you walk away. In Remote view, you can see it and insert ghost items but not real items, and there is no range limit.
