In offline mode I found only one replay named "LastGame.SCFAReplay" located in "\Documents\My Games\Gas Powered Games\Supreme Commander Forged Alliance\replays\ +ingame_(non faf)_username".
But, it was not the last replay, but the previous or even earlier (but today's) replay.

Well, I'll try to get the right replay.

I should note that this is not a new error. This has happened more than once, a year ago. And even earlier, I think.

I sometimes play FAFsupcom offline (run "c:\ProgramData\FAForever\bin\ForgedAlliance.exe" directly).
I choose several cheat bots and play "tower defense"
And I often notice that SMDs sometimes don't work, although I have several charges in several SMDs. They just don't notice nukes and don't shoot at all.

For some reason, this most often happens with nukes from Seraphim ships. But it happens with others too.
This is "BUG"? Is it really possible for the developers to fix this?

Sorry for my English. I used a translator.
