Comment 1 for bug 1734199

did some testing here are my results:

It was definitly one of the changes in r8493 as I tested the provided test game in 8492 and it is loading fine. So I doubt that the issue is about writing the data.
Bug is reproducible in the empire 4 scenario. I did a quick test on a normal map (Einschlag) and there it was not reproducible (saved 3 times, all savegames were loadable).
It is not related to Vesta (aka Player 3) as the game will crash while loading player 2 if player 2 has not achieved basic economy.
I am not sure if this is related to my changes in tribes init.lua and empire.lua will try to port the mission to the new custom load mechanism and try again.
