After updating to new version of Jetpack mod i just pressed J for jetpack and instantly crashed save into menu
Crash report:
The mod Space Exploration - jetpack gui (1.0.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event space-exploration-jetpack-gui::on_nth_tick(4)
space-exploration-jetpack-gui/control.lua:87: attempt to index field '?' (a nil value)
stack traceback:
space-exploration-jetpack-gui/control.lua:87: in function 'gui_update'
space-exploration-jetpack-gui/control.lua:66: in function 'on_lifesupport_gui_refreshed'
space-exploration-jetpack-gui/control.lua:58: in function <space-exploration-jetpack-gui/control.lua:52>

that's unexpected, but I'll look into it shortly.

could you perhaps send me over the save that crashed? it looks a little specific and probably easier to reproduce that way.

There is the save file
