Replay

[Sgt Barker]

First thing I do is quit and restart; that often sets things back to normal speed.

A trick someone posted a while ago that works if the replay ends on F8 (aka, ludicrous speed :)) is to make the first two combat actions be artillery fire done from the artillery dialog. The first shot happens at the high speed, but the second, and all subsequent firing, is then set back to normal speed.

Wierd yes, but it works.
