The actions performed at Christmas are annoying and ruin the game for many players for a week each year

The actions are:

• All water around a player turns to ice
• All dirt with grass around a player turns to dirt with snow
• On the new year, a process is added to slowly remove ice

To make this less annoying, the new behaviour should be:

• Only water in contact with existing ice should freeze
• Only dirt with grass in contact with ice, snow, or dirt with snow should turn into dirt with snow
• The process that cleans up ice and show should be faster
• There should be a "christmas block" that will perform the previous behaviour within a radius of the block, for those players who want the previous behaviour
