[sblock=Far too late to retcon but...]
In a previous round, Soldier was shifted away from a troublesome spot while prone thanks to opening shove. You can't do that.

Prone
• You grant combat advantage to enemies making melee attacks against you.
• You can’t move from your space, although you can teleport, crawl, or be forced to move by a pull, a push, or a slide.
• You get a +2 bonus to all defenses against ranged attacks from nonadjacent enemies.
• You’re lying on the ground. (If you’re flying, you safely descend a distance equal to your fly speed. If you don’t reach the ground, you fall.)
• You take a -2 penalty to attack rolls.
• You can drop prone as a minor action.

I suspected it couldn't be done but I let that one slide at the time because I couldn't find the precise rule in the PHB that prevented it. But the Compendium really is a better tool for this! I started looking it up after the argument that the zombies should have taken additional curse damage after taking damage from Armor of Agathys. Again, I knew that it shouldn't be so but the PBH was letting me down once more. Long live the compendium. always up to date with all the erratas!
Thanks to all the player who have been crawling away from the Hound and taking the OA instead of jumping on the jurisprudence that they could shift!
Of course I won't retcon, it would be a nightmare! But no more opening shove moving prone PCs away.

[sblock=Mri'Thas]
Okay, more details would have been appreciatedl...
By the IC description, it seems you crawled to L6, took an OA then missed with a thunderwave (even though you forgot the -2 for being prone) centered on K8.

The burning effect of the fiery shroud start to die down even though one of the hound still has his pelt on fire. Meanwhile, both zombies at the forefront see their rotten flesh harden and crack under the unnatural cold generated by the warlocks. They are both one solid hit away from shatterring in pieces
But it stops neither the frozen zombies nor the fresh ones from launching in a frenzy. Tsi'Ri takes a solid hit while both Soldier and 7 Rabbit are pressed hard.
The gravehounds ferocity is testament to their bestial nature. Covered in wounds, clearly about to fall apart, they keep pressuring the heroes. Seeing that Mri'Thas is in very perilous position, one hound does not hesitate to go for the throat
Damien urges the zombie next to him to greater feats of strenght but the clumsy monster flails around which sends Damien into a fit of anger.
-''You ****ing stupid ****, just follow through when you ****ing make the jab and ignore her ****ing dagger! You are dead you ****ing ***hole, you don't need to worry about a ****ing light cut!''
With these wise words of advice, the Zombie overruns Tsi'Ris defenses at last and pounds her so hard in the chest she might have broken ribs.
-''Yes! That's how you ****ing do it!''
The wizadress moves carefully into the room, seeing that things are crowded she opts simply to sends a magic missile toward an easy target and despite some jitters still lands a blow squarely on the warriors armor.
