I think there is an incompability with either Shuttle mod or some other train mod since 19, I guess because of a shared variable or something similar, would you mind adding a similar option including something to change names and designate specific trains as shuttle? =) it's completely okay if you don't want to, the mod is great as it is
anyway sorry for the bad bug report, if I update to 0.19 again I will write it down to share, 0.18 worked fine for me (i have a very mod heavy save)
one of a few bugs I encountered is
LuaTrain API call when LuaTrain was invalid. stack traceback: __TheFatController__/TrainList.lua:351: in function 'automatedCount'
__TheFatController__/GUI.lua:165: in function 'get_toggleButtonCaption' __TheFatController__/GUI.lua:399: in function 'newTrainInfoWindow'
__TheFatController__/GUI.lua:328: in function <__TheFatController__.GUI.lua:305> [C]: in function 'pcall' __TheFatController__/GUI.lua:305: in function <__TheFatController__/GUI.luaL:304>
there were others if I remember right and also one with the Shuttle and 0.19 which I don't have in console history anymore
