Problem UCGO cars + DG bug found!

[RisingFury]

I'm posting this in a public thread instead of over PM because I'd like the rest of the O-F community to confirm the bug and be aware of it...

1.) Open "AI cars Dance.scn" scenario in a text editor.
2.) Change the date into the future. I used Date MJD 52006.7896195801
3.) Add a DeltaGlider into the scenario. Use this:

GL-01:Deltaglider
  STATUS Orbiting Earth
  RPOS 4317805.97 1359391.54 4485027.41
  RVEL -426.724 18.891 400.454
  AROT 57.24 36.34 44.57
  VROT 6.99 2.09 -3.81
  AFCMODE 0
  PRPLEVEL 0:0.977501 1:1.000000
  THLEVEL 0:0.887911 1:0.887911
  NAVFREQ 0 0 0 0
  XPDR 0
  AAP 0:0 0:0 0:0
END

4.) Load "AI cars Dance.scn" scenario in Orbiter and you'll get a CTD.
5.) Go back into text editor, switch the focus and camera to:

BEGIN_FOCUS
  Ship DG GL-01
END_FOCUS

BEGIN_CAMERA
  TARGET DG GL-01
  MODE Cockpit
  FOV 50.00
END_CAMERA

6.) Run Orbiter again and start switching between UCGO cars. Within a few focus changes (5 to 20) you'll get a CTD. It only happens with UCGO cars. Date needs to be changed into the future and DG added. So I have no idea what's going on here.

(For anyone who tries it, here's the original date in the scenario: 52006.7883195489)

Orbiter log shows nothing, but it's good practice to post it, so here it is:

This is almost a clean install. OBSP and OBSP MFD were both disabled. The only thing enabled was AutoHideInfoText, but it can't have any influence because we've already confirmed the bug on an Orbiter install without that module.

Here's the default scenario, so you can restore it afterwards:

BEGIN_DESC
AI cars Dance (CTD ? see at end of description)

-----------------------


Just watch the scene as trucks, forklifts and fuel trucks load/unload cargo and refuel the mother ship.


NOTE: You can create complete "dance" around a base where you plan to land. AI cars will be disabled and inactive when you'll be far away and start to "dance" when you'll approach the base.


GOT A CTD ?

-----------------

If you get a CTD after 41 seconds in this scenario it's due to LolaMFD that doesn't support Vessel deletion and so cause CTD with cargo release/grapple - Please Disable LolaMFD

[escapetomsfate]

I can confirm this on a clean install with just UCGO.

What could be the general cause? Must be something wider than the combined DG and time specifically.

 

[astrosammy]

No time to test it currently.

But

BEGIN_FOCUS
  Ship DG GL-01
END_FOCUS

looks a bit wrong... Shouldn't it be

BEGIN_FOCUS
  Ship GL-01
END_FOCUS

?

However I doubt that this is causing the bug...

 

[RisingFury]

For the record, it's not the focus line that's causing this bug. It can be resolved by switching time into the past.

I'm just curious why it would crash - what is it about the DG / UCGO / date combination...

 

[Izack]

Could it have something to do with the car AI dance being time-dependant? Can't see anything about it in the scenario, though... :shrug:

 

[elocoreloco]

Within a few focus changes (5 to 20) you'll get a CTD.

I get the same problem but when i'm focusing an XR5, when i try to switch from one XR5 to another XR5 i get the CTD, but once i get that CTD i can't load the scenario, keeps crashing, then i edit the scn file and change the focus to ISS and then it loads normally until the next few focus switching on the XR5's.

PS: I got one AI runing for this scn file.

 

[RisingFury]

It seems to be caused by UCGO. All these failures gravitate towards it, but it always need a catalyst for the CTD to occur.

My guess would be the AI also. I can't really think of anything else :S
