I have run into this error across two saves now. The first was modded so I did not report or record anything anything, I also did not have a backup of the non-corrupted save for it. This report is about the second game. The second game was created using a fresh install of Aurora v2.1.1 downloaded from the forums, it is completely stock and in a different folder. Four things each game had in common:
1. Earth Death Spiral 0.03AU
2. Loaded a Medal Set
3. Started at year 1
4. Deleted Starting Colony on Earth, created new colony in randomly generated system with a Colony SM edited in. SM added a single large ship to the new colony.
When this first occurred I went to check on Earth around Aug 0027 saw NaN in its Distance and temp columns under System Generation and Display. Luna also had a NaN number but I cannot recall the column. Out of paranoia I saved and restarted the game, that's when I got the 1170 error on load. I was able to restore a windows backup that was good with the game time of Aug 0023. I ran time forward and Earth eventually vanishes and shows up with a NaN in the System Generation and Display Window and vanishes from the tactical map. I save and upon reload I encounter Error 1170. The #1170 error did not occur in Aug 0027 as it did previously, it occurred around Dec 0032 this time. I restore the same backup save from Aug 0023 ran the game forward for a second time. Earth's orbit on the tactical screen gets more and more eccentric before it vanishes, this time around Mar 0033. I save and upon reload I encounter Error 1170. While attempting to recreate the error I noticed some odd things. As Earth gets closer to Sol its orbit is drawn more and more eccentric on the tactical screen but when restarting the game it appears nearly circular. I have two screenshots attached showing this before and after reloading the game. The Eccentric value is listed as 0.017 in the System Generation and Display window and did not change at all during my testing. While taking these screenshots I restarted Aurora and also created a backup of around Jul 0031. Running time forward again the error did not reoccur until Mar 0033. I restore the Jul 0031 copy of the db and this time deleted Luna and Earth immediately. I was able to make it to Mar 0034 without the error occurring. I restored a copy of the Jul 0031 db again without deleting Luna and Earth, I encountered the error again around May 0033.
I have attached two databases to this post. One is the corrupt DB named "AuroraDBcorrupt3mar0033.db", game time should be around Mar 0033, all but one planet is missing. Second is a backup of "AuroraDB - Copy (3)Jul0031.db", game time should be around Jul 0031, game is normal, and all planets present. If you enable auto turns and run time forward everything should occur sometime around March to May 0033. DO NOT close aurora when attempting to recreate this error, it must be done in one go.
