Sliding ice as event

[DarkGrey]

I'm trying to set up sliding ice as an event that appears only during the winter. How would I go about that?

I'm not sure we can change a terrain tag via an event. If I had to do what you want, I would duplicate the map and make a winter version of it. And change the teleport events to access the map only during winter. Of course if you have other maps with transitions, then you'll have to do a winter version of them too.
