Ice walking and underground city mobility removed?

[MrWakaWalrus 3]

For the ones who play rpt since 2010 and played during xmas will notice that underground city moving and ice walking has been removed. I was waiting for those so badly I loved to walk under the city unoticed and go far away from ricarten by the frozen water...

 

btw, a question: I've misplaced my tree somewhere I didnt want it to be. Is there anyway to replace it? I tried buying another but it says I've bought one already and disappears.
