After a while of playing my save game with the timetables mod i now load my save game, make a new line but when i open the timetable tab the game crashes instantly with the following error:

Uncaught exception while in class UI::CSelector
Exception type: Lua exception

This error is usually caused by modding. Some game resources contain incorrect data.
