reported Slave All to SPI fails most of the time

[LeCuvier]

When I use the APKWS rockets I like to designate the target from the TVV. I use these steps:

From TVV (Total Velocity Vector), with TGP on Right MFCD   Set HUD as SOI Throttle Coolie Hat Up Short Slave TDC to TVV Throttle China Hat Aft Short Manoeuvre TVV near Target         Ground-stabilize the TDC Stick TMS Forward Short Make SPI Stick TMS Forward Long Slave All to SPI Throttle China Hat Forward Long After these steps, I set the TGP (right MFCD) as SOI etc. I have been using this process for a long time without problems. But several updates ago I started seeing this failing. When I push the China Hat Forward Long, the SPI simply disappears. Note: It doesn't fail every time, but now most of the time. As a work-around, I set the TGP to boresight and create the SPI from there. But I would really like to use the TVV. I attach a track.

A-10CII cannot SLAVE ALL TO SPI.trk
