My problems with simultaneous

[PvK]

I just ran a test in 1.84 & Props 2.4.2 and didn't see a problem. I made a cruiser with efficient ion engines for usual speed 3, and strapped on Emergency Propulsion 5, gave orders to use the component and move, and it zoomed at speed 8, to 8 sectors away.

Hmm, I guess I should test with your colony ship example.

Ok, yep, I see the same thing. This would be a new bug discovery (congratulations...). Also, I don't understand what causes it. If I make a speed-3 colony ship with Emergency Propulsion II, and use it, it DOES go 5 sectors.

Let's try speed-1 and EmProp V... nope, same blown component and speed 1.

Ok, let's try a cruiser with speed 1 and EmProp V... nope, goes 1 and blows.

Seems like it is speed-1 ships. Let's try speed-2 ships with EmProp 5. ZOOoom... went 7 as hoped.

Testing with a speed-2 colony ship with EmProp 2 - goes 4 as expected.

Sooo... seems like there is a "feature/issue" wherein ships must have at least regular final speed 2 or more, or emergency propulsion won't work. I think the manual says somewhere that it has to have at least 1. So either it's a mistake, or I'm misremembering what the rules say.
