GBUs: What am I doing wrong?

[Zone5]

Trying to get GBU 10s and 12s to guide. I've tried multiple missions (including one I made just for this purpose with the way point at the target on the ground). Static targets, moving targets it doesn't matter. I think I'm doing it all right:

Altimeter set
INS aligned (with ground start...)
TGP active
A-G Mode
Master Arm ON
Laser ON
Laser code set (1688 and I've tried others...)
Laser code set in DED
Autolase set in DED (8 sec, 10 sec, 12 sec, 15 sec and even 30 sec)
CCRP
NSTL Fuse
RPL 1
Rel Ang 0 (or 45)
TGP SOI
Target set in crosshairs (TMS UP/Point or TMS Right/Area)
ON Steering cue
Weapon away at drop cue
Laser comes on at correct time
Follow target on TGP MFD
Bomb flies OVER the target to land in the dirt 1000-1500 yards beyond the target EVERY bloody time.

I'm sure I've missed something, but 2 days of looking at Chuck, the Manual, MANY YouTubes, and I can't think of anything else.

Like the title says...what am I doing wrong or missing?

Any help would be appreciated.

A track replay would help us get a look at the process to see if anything is missing or user error.

That would take about 25 tracks, which is why I didn't send any in the first place, but I see your point.

In any case, I finally figured it out--it was a mod (specifically the VSN F-4B/C) which was removing all my REDFOR groups at start up. Apparently this showed up with 2.9.14.8222 last WED. I don't run many mods (and I can live without this one) once it occurred to me that a mod might be messing things up, it only took an hour of rerunning with and without specific mods to find the one that did it.

My goal was to learn the GBU procedures--I think I now have them memorized...

Thanks!

My guess is you're releasing on the toss cue and not the straight and level drop cue. When toss was introduced I tried using the 0 for toss angle as well but found that not to equate with the normal release cue.

Glad you figured it out. I was going to say that years ago I had a similar issue with LGBs landing all over. Turned out it was the map…I had never deleted the contents of my FXO (and whatever the other one is) file like you should after each patch. Doing so did the trick

I had the exact same problem recently and I was going crazy. In my case, the problem came from the NSTL fuse — it had to be switched to NOSE for it to work. Also, make sure that the TGP remains SPI until impact, I sometimes had bugs where it designated itself. And finally, avoid maneuvering too much after the drop, it seems to disturb the trajectory. Since I've been doing this, my GBUS have been hitting the mark.

NOSE for an LGB should dud the bomb. The nose fuse well is taken up by the battery for the guidance system. NSTL or TAIL has worked with 100% reliability for me.
