Take a row on nuke launchers and fire them at one, they all die on the spot. Nothing launches, the nukes don't go off, the launchers just die. This has happened in 3 different games now.
I haven't had the nukes and nuke launcher disappear at launch but i have had nukes not begin building after i launch one no matter how many i add into it or stop / start it. Also have finished an anti nuke and not been able to build the other 2 on it.
Last night I also tried to launch a nuke through PiP and it went up and came right back down on top of me. Still haven't experienced your issue though.
