T3D 1.1 beta3 - Lightmap size cannot be made smaller inside the World Editor - RESOLVED

T3d 1.1beta3
Win7
Editors -> World Editor -> Terrain -> Lightmap Size
Repeat
In World Editor select the terrain and then move the lightmap size up using the up arrow key/button. It goes up nicely in 256/512/1024/etc but doesn't go down - it attempts to drop by a single digit but then fails. Works fine if you type the value in.
Suggest
Make the down value work in jumps of 256/512/1024/2048/can't remember the proper name/etc, like the the up arrow does
Fixed in stock 1.1 Preview 10 april 2011

Thankfully the Bunny Shoe chick will divert my attention soon enough.
I wish you were testing my game, too.
Edit: ... and all these reports are also LOGGED already! How cool is that?

Edit the following function in terrain/terrData.cpp:bool TerrainBlock::_setLightMapSize( void *obj, const char *index, const char *data )
{
TerrainBlock *terrain = static_cast<TerrainBlock*>(obj);
// Handle inspector value decrements correctly
U32 mapSize = dAtoi( data );
if ( mapSize == terrain->mLightMapSize-1 )
mapSize = terrain->mLightMapSize/2;
// Limit the lightmap size, and ensure it is a power of 2
const U32 maxTextureSize = GFX->getCardProfiler()->queryProfile( "maxTextureSize", 1024 );
mapSize = mClamp( getNextPow2( mapSize ), 0, maxTextureSize );
if ( terrain->mLightMapSize != mapSize )
