This mod seems to result in a lot more stuck trains than its predecessor. The behavior I'm observing is that the crane won't unload if it still has items "in hand" when the train leaves, even when space is available, and it also won't put the items it has on hand into the train until the hand fills, even if that's taking a very long time. My guess (and I'm not a Factorio modder and haven't tried altering the code to see if it matters) is the behavior that is enabled with "wait_for_full_hand = true" is the culprit here. Is there any chance that could be either false or configurable behavior?

I can add setting to turn on/off this behaviour. For me it's an advantage.

Thank you so much for addressing the issue. I have run the mod for a few hours now with the setting disabled and almost no stuck trains, where before I was spending a great deal of time chasing them down and clearing partially full cranes. I can see where it might be less of a concern in a larger factory.
