Possible misbehaviour on a still unknown Add'On with KSP-Recall

[Lisias]

Fellow Kerbonaut hugoraider is being screwed by what appears to be a misbehaviour triggered by an unholy interaction between KSP-Recall and (probably) B9PS.

The problems happens only when merging an existent craft into the current one. The misbehaviour is remarkably similar to what happens when AttachedOnEditor is needed but it's absent:

Craft file: Vega 3.craft.zip

This craft needs:

• Bluedog DB
• Conformal Decals
• New Tantares
• Tantares
• Tantares LV
• Tantares SAF
• Tantares SP
• Gemstone LV (not sure)

Most dependencies weren't installed (on purpose). Only Shabby (and 0Harmony), due Conformal Decals, were installed while reproducing the problem as below:

What more or less matches the screen shot provided by the user.

Mission: Search and Destroy (the bug)

Removing Not My Fault as it's too soon to be sure about. (added it by accident)

[Lisias]

It worths to be mentioned that the Attaching Nodes are completely missing on the merging craft - what apparently suggests that B9PS was the one initialising them - what suggests we have a problem similar to the one on Procedural Parts ( #41 ).

[Lisias]

Found something weird. With all the mentioned add'ons installed (with all the dependencies), I found that the problem I detected on my rig was due this exception:

[LOG 09:32:53.539] [KSP-Recall.AttachedOnEditor] TRACE: RestoreCurrentAttachmentPoints for <NO VESSEL>-HeatShield0:FFE5DB88

Happening where AttachedOnEditor was working on the HeatShield0. But this part is a Stock one, and once I removed all that add'ons, this part behave while merging a craft with it.

So we have someone screwing up things here. And it's not me.

[Lisias]

It's weird and almost surely unrelated.

I edited the craft file to replace HeatShield0 with HeatShield1 (this last part doens't borks), but the problem remains. So this NRE is not causing neither affecting the problem.

[Lisias]

On the other hand…. A huge crapload of Exceptions are being thrown by the Part Loader:

KSP.log.zip

Let's remove the affected parts and see what happens...

[Lisias]

So, I removed the following directories

• GameData/Tantares/parts/z_deprecated_3
• GameData/Tantares/parts/z_deprecated_4
• GameData/Tantares/parts/z_deprecated_5
• GameData/Tantares/parts/z_deprecated_6
• GameData/Tantares/parts/z_deprecated_7
• GameData/Tantares/parts/z_deprecated_8
• GameData/Tantares/parts/z_deprecated_9

as well also:

• Tantares/parts/core_pirs/_mira_crew_s1_1.cfg
• Tantares/parts/core_polyus/_rotanev_aeroshell_s2_1.cfg
• TantaresSP/parts/core_ye8/_ye8_solar_s1_1/ye8_solar_s1_1

Not all z_deprecated parts were at fault, but a huge load of them were, so I took some shortcuts in order to hush the diagnosis. I removed them all. :)

But yet, nothing changes. The problem is still there. :(

[Lisias]

Oukey, with the KSP.log clean from Exceptions, now I gone to the good and old Trial and Error.

And found that Tantares/parts/code_almaz/_grus_crew_s2_s1p5_1/grus_crew_s2_s1p5_1, Grus Size 1.5 Fuselafe, is the one borking on me.

[Lisias]

Found another one that causes problems: Tantares/parts/code_almaz/_grus_adapter_s2_s1p5_1/grus_adapter_s2_s1p5_1, Grus Size 2 to Size 1 Adapter.

Interesting enough, these two parts has fairings by ModuleProceduralFairing. I may had find a pattern.

[Lisias]

Oukey. So I removed SimpleAdjustableFairings and B9PartSwitch (as it complained about SAF) to see what happens.

Unsurprisingly, same problem. Whatever is happening, apparently is related to ModuleProceduralFairing.

[Lisias]

So, it's related somehow to ModuleProceduralFairing, and now I need to check if it's something related to AttachedOnEditor interacting with it, or if it's something wrong with the "Grus" parts on Tantares.

So I made this craft :

Using a Fairing as root. merge test.craft.zip

And it was merged all right:

Variations of the merge test craft worked as well, as long all the parts involved were stock.

So, no. There's no conflict between AttachedOnEditor and ModuleProceduralFairing.

So whatever is happening, is on Tantares for sure.

[Lisias]

~Temporary workaround~: [EDIT: DIDN'T WORKED]

GameData/__LOCAL/KSP-Recall/Tantares.cfg

@PART[grus*]:HAS[@MODULE[ModuleProceduralFairing]]:FINAL
{
    -MODULE[AttachedOnEditor],* { }
    -MODULE[TweakScale],* { }
}

[Lisias]

I bluntly removed every part that was throwing an Exception on KSP.log, no matter how silly was the Exception or where.

I removed AttachedOnEditor and TweakScale from the affected parts (the Grus thingies with ModuleProceduralFairing.

Tailored a simplified version of the test craft. Vega 3 kpado.craft.zip

And got this:

Conclusion: The AttachedOnEditor is needed on the affected parts, otherwise we see the parts scattered around as demonstrated by the screenshot. But something broken on some Tantares parts (and there are a lot of broken parts, as it appears) is screwing up with KSP-Recall.

Exactly what I'm unsure if I should purse, because it's not up to me to fix every single broken AddOn on the face of Kerbin.

[Lisias]

I think this may be related to #66 too (crafts appears to be rerooted before being merged).
