[FIXED] Lemmings may survive nuking [BUG] [PLAYER]

[Nepster]

Sometimes some lemmings may survive nuking. I currently don't know what causes this bug or even how to reproduce it. Here my current knowledge:
- Every time I encountered this bug, I did some heavy frame-stepping during the count-down.
- This behavior cannot be caught in replays. If you encounter this behavior and save a replay, everything works as intended upon loading the replay.

Note: This happened when testing the non-released experimental new-formats version of NeoLemmix. I don't know whether this occurs as well in the V1.47 versions.

I have been able to reproduce this on new-formats branch, but not on V1.47n-D (and thus presumably not on any other backwards-compatible branch either).

Confirmed this is still occuring in commit 69C4598 (latest at the time of this message).

It would appear to be somehow related to save states, as I can only get it to occur when an internal save state would be made during the countdown starting.

EDIT: Can also confirm that it is occuring on the backwards-compatible branch, now that I have a rough idea of the timing to trigger it (still none on the exact causes).

EDIT: It would appear it's triggered much more easily than we thought - simply trigger the nuke such that the assigning of bomber-countdowns crosses a 10sec mark on the timer (as this is when savestates are made), then perform a backwards frameskip such that both the start and end points of the skip are after said 10sec mark. From what I can tell, this consistently reproduces the bug with only a single frameskip. The lemming that would've begun counting down on exactly the frame of the savestate, and all later lemmings, will not get countdowns.

Found the cause! It should be fixed in commit BD770DE.
