I checked the game archives, looking back 3 weeks, and don't see where you had them. Your nation strength trend chart also does not indicate an overnight loss of nukes looking back 4 weeks.
Your citizen income is currently $600.51. I added 2 Guerilla camps to your nation and your citizen income reduced to $504.43. Are you sure that you didn't see $504 as $604?
Looks like the game sent duplicate messages but did not process the second defeat alert against the other nation. Checking into the duplicate message issue.
