Sometimes you don't remember where you died or were AFK at the time. This adds the sector and cause of death to the insurance email.
Edit the Avorion/data/scripts/entity/insurance.lua file and change the section near line 359 from:
local mail = Mail()
mail.header = mailHeader
mail.text = mailText
mail.sender = mailSender
mail.money = refundedValue
to:
local lx, ly = Sector():getCoordinates()
local deathInfo = "Sector: (${sx},${sy})\nCause: ${cause}\n\n\n" % {sx = lx, sy = ly, cause = Faction(damagers[1]).name or "collision"}
local mail = Mail()
mail.header = mailHeader
mail.text = deathInfo .. mailText
mail.sender = mailSender
mail.money = refundedValue
Only the first contributor to your death will be shown, so if you were being attacked by two different factions the email will only display one.
