Did launching suddenly become harder?

[Mitchz95]

For some reason, since I started playing today I've been having extreme trouble getting anything into orbit. My normal launchers, which could easily carry their designated payload masses into orbit, are now incapable of even getting my apoapsis above the atmosphere. I need at least 5,500 delta-v to get into orbit now.

Is there some kind of new bug? Or has the Kraken somehow mutated?

Perhaps you could explain your lifting strategy for getting to orbit? It shouldn't take more than about 4,500 dV in most cases, unless your TWR is particularly abysmal early on.

[Kasuha]

Did you change anything on your computer, on the game, or on the way you are playing it?

Because the code of the game did definitely not change since yesterday.

[TheDarkStar]

Did you add any mods?

[MajorThomas]

Any chance you're using MechJeb and have your thrust limited to something smaller than 100%?

[Mitchz95]

I usually limit my initial thrust so that I hit 150m/s at 7,000 meters up, then begin my 45 degree gravity turn at 10,000 meters. Once my apoapsis is above 70km (usually 80) I cut my engines and set a maneuver node for the orbital insertion.

I've been using this tactic every launch for weeks and it's worked like a charm. Nothing has changed on my computer.

Well then, in that case, everything should be as before, shouldn't it.

Also, post #1111.

Has anything changed about your launch profile at all otherwise? Lower TWR, less aerodynamic rocket structure, possibly you've added or taken away control surfaces? Or is it literally a case of "this exact same rocket launched fine last week, yet doesn't launch right at all this week"?

[katateochi]

I have had some very rare cases when things just would not work, things that had worked perfectly before just failing, again and again. It felt like the game was having a bad hair day. Restarting the game (sometimes also restarting my computer) returned things to normal.

These have been very very rare and impossible to determine what the cause was or even if it was not just me being the problem. But perhaps something failed to initialize during loading, or maybe a graphics card setting was temporarily changed, who knows.

All I can really say is the age old "have you tried turning it off and then on again?"

[Seshins]

Had an issue where my 75 ton LKO lifter which has worked flawlessly for the past 20 or so launches, suddenly couldnt even make a 70km apoapsis before i had to stage. reverted to launch and attempted it again and it worked fine.

^^ You should make that an achievement.

If your kerbin seems to have acquired an extra 1000m/s of dV necessary to make orbit, something is seriously wrong. revert, restart, reboot. Universal troubleshoot sequence. Give KSP a restart and if that doesn't fix it, you are in serious trouble.

it happens sometimes, maybe its a bug but hey, beta game is beta, when it happens tome i revert launch and try again, if still happens i just restart the game

[TNM]

Sometimes, when the launchpad loads, it breaks the rocket. Reload and it should work. This is especially true for large, unstable rockets (not strutted enough).

[The Destroyer]

Perhaps the crafts file somehow broke, and some struts/fuel lines broke, breaking the rocket.

[Boosterspice]

As TD said, the alleged fuel line(s) may have broken. Apart from that, mechjeb has some bugs too, so if you use mechjeb a lot, try to download the newest version (do it again, even if you already have it) and install from scratch.

[Mitchz95]

Thanks for all the responses, guys. Things seem to be mostly back to normal now, so I guess it was just a bad day.

[csanders]

With the new version, inside the VAB, one could also accidentally click on an engine and reduce its thrust. Another thing to keep an eye out for.

So we should just ignore it? Some help that turns out to be.

We should really be trying to figure out where the source of the problem is so that the devs know what needs fixing. This is after all, what beta testing is all about.
