The mod Renai Transportation (2.0.1) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event RenaiTransportation::on_nth_tick(1)
RenaiTransportation/script/MiscFunctions.lua:451: attempt to index field 'character' (a nil value)
stack traceback:
RenaiTransportation/script/MiscFunctions.lua:451: in function 'GetOffZipline'
RenaiTransportation/script/players/on_tick.lua:325: in function 'handle_players'
RenaiTransportation/script/event/on_tick.lua:6: in function <RenaiTransportation/script/event/on_tick.lua:5>

That's probably due to me changing the way zip lines work behind the scenes to get it 2.0 compatible asap. Hopefully when I refine it more this will be fixed
