Hello, I am playing TFMG and I'm unable to drop another scout'o'tron onto Arrival.

2841.479 Error MainLoop.cpp:1468: Exception at tick 563196: The mod Orbital Vehicle Deployment (2.9.4) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event spider-launcher::on_gui_click (ID 1)
__spider-launcher__/scripts-sa/map-gui.lua:1239: attempt to index field 'temp_deployment_data' (a nil value)
stack traceback:
    __spider-launcher__/scripts-sa/map-gui.lua:1239: in function 'show_extras_menu'
    __spider-launcher__/scripts-sa/map-gui.lua:1904: in function 'on_gui_click'
    __spider-launcher__/scripts-sa/control.lua:195: in function <__spider-launcher__/scripts-sa/control.lua:58>

Specifically, I have loaded it with some solar panels and roboports from the virtual menu, then clicked the green crosshairs button when it crashes.

Merry Christmas, sorry that you were experiencing bugs, this didn't happen every time but I did manage to replicate it once.

The issue was the temp_deployment_data was being used before it was initialised, so I've corrected the order and you shouldn't experience this bug. Fixed in the latest version
