So, the next question is, "Are they going to be active all year or be deactivated eventually?"
The same question was asked in the other christmas gift thread (entitled ":::Spoiler::: The Christmas Gifts are Great! Thank you Devs!") and this is what Regine said:
Q - Will we be able to use the Christmas tree deeds all year long to set up bare trees?
A - Unfortunately no. Since we do not want players having Christmas tree up year round, the trees will redeed as usual past a certain date.
Thinking of it though, I might be able to only make the bare trees available past that date. In which case you would be able to use the deeds year round but only have access to the decorated trees during the holidays.
I'll look into that. But obviously you're not getting that this publish. Maybe 58, but no promises.
