Dont know if this is known already...
I play with SE 0.6.87

The mod Scan Area (1.0.2) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event ScanArea::on_player_selected_area (ID 51)
ScanArea/control.lua:38: attempt to compare nil with number
stack traceback:
ScanArea/control.lua:38: in function <ScanArea/control.lua:1>

What area were you in when you got this error?

I was in Nauvis Orbit.

I know this is super late, but: this should be fixed now.
