As the title suggests, the moborigins:snow_trail power does not work as featured on the Wiki in this version. This was tested using the following code, which is essentially the same power as the Snow Golem's trail:

{
    "type": "apoli:multiple",
    "toggle": {
        "type": "apoli:toggle"
    },
    "trail": {
        "type": "moborigins:snow_trail",
        "condition": {
            "type": "apoli:power_active",
            "power": "*:*_toggle"
        }
    },
    "name": "Frost Trail",
    "description": "Leave a trail of snow behind you and turn water into ice when walking over it."
}

Not sure if this is intentional or not, as I cannot find any patch notes that would indicate that the power no longer exists.

Just fixed this, It'll be in the next release, in a day or two just in case any other bugs are discovered.
