The Soyuz side booster tank has an error in its config

[fourfa]

The Soyuz-style tapered side booster tank (FL-C1000) has an error in its config file.  The stock Size1p5_Tank_05.cfg (in GameData/SquadExpansion/Making History/FuelTank) contains the lines:

CoMOffset = 0.2, -1.0, 0.0
CoPOffset = 0.25, 0.5, 0.0

Presumably to put the center of mass and (I assume) center of pressure away from whatever the model origin is.  The result is this:

And when attached Soyuz-style to a rocket and staged away, the behavior is as follows:

I wish I could take credit for realizing where the problem lies - the Twitch streamer @DasValdez today immediately guessed that one of the offset axes had accidentally been flipped at some point.  I made adjustments in the following patch: 

// Adjust centers of mass and pressure of FL-C1000 'Soyuz' fuel tank in KSP Making History for 1.4.1
// Author: Fourfa
// x, z, y relative to VAB door?

@PART[Size1p5_Tank_05]:FINAL
{
	@CoMOffset = 0.0, -1.0, 0.2
	@CoPOffset = 0.0, 0.5, 0.25
}

Note that I have simply swapped the values in the first and third rows.  With zero other changes made to rocket or flight path, the following is the result:

If you've been wondering why you don't get the expected symmetric Korolev Cross, this is why.  Hope this helps.

Thanks for posting this, fourfa! I really appreciate your fix. Hopefully this gets added to 1.4.2 soon.

Hey! I posted about this last Wednesday!  What took him so long?

Dang it, I knew I’d seen a thread like that somewhere. Too many sub forums to check now

Yes, perhaps another subforum or two would help.   What I am doing is putting what I consider confirmed bugs in the Support subforum, and issues that are up for debate I am putting in the discussion subforum.   Indeed, there are currently threads in PC Tech Support, Game Suggestions, Making History General, Making History Support, and of course General Discussions; all over the joint for sure.

This fix works great, I can confirm as much.

No change in 1.4.2. Patch still fixes the issue

No change in 1.4.3. Patch still fixes the issue

For an obvious bug thats been reported 2.5 months ago, and somehow missed being included in 2 different patches, I wonder if it's been forgotten?  Its literally a 35 second fix for the developers, not exaggerating.

 

Please, if you have an account on the bugtracker, upvote, comment, somehow bring more attention to this being skipped:

Do we want to place any bets as to whether this will be addressed in the 3rd patch for Making History?  I checked with Vegas, its 5/1 odds.

Yea...this is annoying...not sure what they're doing over there. 1.4.3 is unplayable for me due to the fairing issues - both the aerodynamic and visual glitches make every rocket I launch looked wrong and perform poorly.

The bugtracker has had it listed as "Being Worked On" since 3/29/18... and its literally just changing a few numbers in the .cfg file.  I am not sure what's going on either.

1.4.4 this week!  Don't forget to place your bets on whether this will be included!  Vegas has it at 7/1 now!

I see nothing in the 1.4.4 patch notes indicating a fix for this, but indeed Size1p5_Tank_05.cfg now has exactly the swapped values fourfa posted in his fix.  Can anyone else confirm the stealthfix?

It took exactly 100 days for this fix, but apparently it has in fact happened.

I tested it yesterday and it looks like it's working
