[Bug]: Nuke load status resets to zero

### Describe the Bug

I had at least five games recently where the nuke load status just reset to zero "randomly". Now I say randomly because I can't figure out why. In game 27714550 I had multiple of these resets (19:01, 19:16, 20:26, 20:40, 22:40, 23:35, 23:45, 23:50, 25:37, 26:16). I only noticed it after the previous patch (3838). In game 27739157 it happened at around 25:26. My mods for reference:

I also see engineers frequently stop assisting the nuke, I don't know the reason for that behaviour. Not just when the nuke load status resets.

### Reproduce the bug

No idea, seems to happen around an assist command.

### Screenshots

_No response_

### Additional context

_No response_

The report names no source file or test; begin by investigating the assist-command handling and the nuke load-status behavior around the reported game times and patch 3838. Reproduce the reset and engineer-assist stoppage, then identify a reliable trigger and add coverage or a fix that prevents the status from unexpectedly returning to zero.
