There is a bug in the game's "
Aria: Eclipse" mission where
Spoiler:if you decided to not free Sederis and convinced her second-in-command to assume leadership of the Eclipse the necessary conversation with C-Sec will not trigger
and renders this mission and Aria's mission arc glitched and incompletable.
It took me a while to find a fix for this, "SqurlGoneWild" at the BioWare Forum
Link created a program that patches glitched saves, allowing you to complete Aria's mission arc without having to miss any storyline!
I tried it myself and had
no problems completing the mission. Although I would suggest backing up any saves before you modify them!
Hopefully this helps anyone that has had this problem.
Save Fixer: Link***If you want to fix the game manually, SubaruH figured out here
Link than you can:
Spoiler:"0. Back up your save files, and make a save in front of the Eclipse second in command. (Sayn)
1. Get a hex editor (I used XVI32) and a Mass Effect checksum calculator (www.mediafire.com/?wmkztjwjimt)
2. Open the latest save in the hex editor and search around for the hex number "00 00 00 D0 00 00 00 00" (mine was at around 0xBAFF) (if anyone knows how to calculate this better, please speak up)
3. Add 0x368 to the address of the D0
4. Around that new address there should be something like 11 89 01 00
5. Change the 89 to 09
6. Save.
7. Open the file in the Mass Effect checksum tool
8. If the checksum it generates has 8 'f's in front of it, remove them
9. Change the endianess of the bytes of your checksum(if on PC...xbox users don't need to, but have to go through the process of exporting their save from the xbox ). If your checksum is AABBCCDD it will become DDCCBBAA. 12345678 becomes 78563412. Et cetera.
10. Modify the last four bytes in the save file to match the checksum
11. Save
12. Load the modified file in ME3
13. Pray to the Goddess
14. Enjoy your fixed game. The quest should complete after talking to Sayn and going to the exit. If not, reload and try again."
However, I suggest using the program that will do the hex editing for you since it's not only easier but less likely to screw up your save.
