Here's your problem, Bloodhunter (from RuneI.RunePlayer):

//================================================
//
// IceStatue
//
// Used only for Ice Powerup
//================================================
State() IceStatue
{
.
.
.
	function InventoryNormal()
	{
		local Inventory inv;
		local int ix;

		// Transform inventory if visible
		inv = Inventory;
		while (inv != None)
		{
			if (!inv.bHidden)
			{
				for (ix=0; ix<16; ix++)
					inv.SkelGroupSkins[ix] = None;
				inv.SetDefaultPolygroups();
				inv.bSweepable=inv.Default.bSweepable;
			}
			inv = inv.Inventory;
		}
	}
.
.
.

Since subclassing each pawn probably isn't practical and

native(610) final function			SetDefaultPolygroups();

is a native function, you'll have to make sure the default polygroups are set to snow; how exactly to go about that, I'm not sure.

Did you try setting each SkelGroupSkin in the default properties?

hmm k .. can u too write me a script that it returns the skelgroups if the snowball flys... in the bwaterzone...??

// Where u found that Ice Statue Class?
// U exported it ?

yep allready done... SkelGrou......
