This means we can fix it by repacking the rezzer and reversing the order the prims are selected, but only if we know this is intended future behavior expected. Otherwise it is simply an enormous amount of hours wasted to work around a bug. We need info on this ASAP so we can decide how to proceed.

Historically, when using llRezAtRoot() with coalesced objects, the FIRST selected linkset has determined the relative position of all other selected linksets.

Now, it appears that this has changed to the LAST selected linkset, but only on sims running the Havok4 code.

Repro case:

1. Rez any number of prims, and shift-select them.
2. Take into inventory
3. Drop the following script into another prim:

default {
on_rez(integer s){ llResetScript(); }
touch_start(integer total_number)

}

4. Drop the coalesced object from 1) into prim from 3)

Observation: Whichever prim/linkset was selected LAST rezzes at the center of the rezzing prim.

One wonders if this might be related to the Havok4 fix for SVC-1449.

Yes, fixing SVC-1449 broke this.
