Yggdrasil without a forest? Crazy talk!

How would I set it in my local copy of EITB so that Yggdrasil is always forested?

In the XML under improvements, find Yggdrasil. There's a field called FeatureMakeValid, and you should be able to set Feature_Forest to 1. That is already set however. Fall from Heaven added a bRequiresPeak tag to improvements, and I think that something similar would be necessary to force Yggdrasil onto a forest - so sadly beyond an XML only tweak.

Thanks for the answer!
