I got the UBM add-on yesterday. I still haven't really played it yet. Yesterday and today (today has been awful, nothing is going right and it seems like I break everything I touch), things have been popping up one after the other. Maybe a little bit later I can finally do a patrol. At least I got it modded and ready to go.
Here's an edit:
Apparently I can't keep from breaking stuff in the virtual world, too. First, I dive too deep messing around with the IXD2. Then, when I reloaded I forgot to click the resume course button. Neddless to say, when I finally did click it, I veered far enough off my original course that I smacked into a small island in the middle of the fricken Indian Ocean! Nothing gets your attention quicker than when you are sailing along nicely at 8192x TC and then BAM!!!! Things blow and break. The screen spins in circles and then I see my U-boat smack dab in the middle of said tiny island.
Maybe I better cut my losses for the day and leave the computer.
