WTF ... Is this normal for the Firewalker missions?

I play on Xbox, so my journal looks a little different than yours. As a thought, though, did you forget to do a manual save after returning toNormandy and are actually now loading a save on Normandy just before going to Zeona? (I've made that mistake before).

You can also check your galaxy map. Does it show the place tags for the other Firewalker missions. If not, then you do probably have to do Zeona over again.

Sorry, that's all I can think of.  I'm just through Firewalker in one of ME2 games.  I can't take screenshots (since I'm not on Facebook to upload them from the Xbox), but my journal has Projecct Firewalker: Rosalie Lost dimmed and shows a "Complete" when the entry is opened.  So, it's definitely not normal.

Is the email still in your Archived Messages mailbox?  Is the hammerhead in the cargo hold?

Another thought (I'm just blindly throwing out ideas here)... I'm not sure if there is a maximum number of saves on the PC.  On the Xbox, there is a definite maximum (I think it's around 30 for ME2).  On the Xbox, we just can't exceed the maximum and have to delete an old one to save the new one once the maximum is reached... but maybe the PC is different and the game just starts to have trouble acknowledging saves over the maximum number.

Sorry, I'm not more help.  Hopefully someone else on PC can help you figure it out.

* Well I tried it a second time by redoing the Zeona mission ... same odd thing happened? 

* After that I tried one last time ... and in this case it all worked out some how. Did the same things as with the previous two tries, yet oddly enough this time I could do and finish all the Firewalker missions?   This was a really odd thing that happened, I hope it does not happen again.

* Oh and just after having finished all the Firewalker missions I went back to Omega so I can get Archangel. There I found out that the total savegame amount on PC is apparently 51, I hat to delete several savegames before I could save on Omega. ( Well deleting one was already enough, but hey why not. )
