Was copy-pasting rails, the following crash happened:

29551.878 Error MainLoop.cpp:859: Exception at tick 26049145: Error while running event cut-and-paste::on_tick (ID 0)
cut-and-paste/control.lua:48: attempt to index local 'm' (a nil value)
29551.878 Error ServerMultiplayerManager.cpp:94: MultiplayerManager failed: "Error while running event cut-and-paste::on_tick (ID 0)

29551.878 Info ServerMultiplayerManager.cpp:670: mapTick(26049145) changing state from(InGame) to(Failed)

I received essentially the same error in single player while trying to copy/paste and cut/paste rails.

Error while running event cut-and-paste::on_tick (ID 0)
cut-and-paste/control.lua:48: attempt to index local 'm' (a nil value)

398443.665 Error MainLoop.cpp:864: Exception at tick 33234812: Error while running event cut-and-paste::on_player_selected_area (ID 49)

Thanks, both issues are fixed in 0.1.4
