Thanks for the report, I got so used to skipping this mod when updating the others that I forgot to update it with the changes for DF 52.

Getting these errors in the error log:

MAMMOTH:Unrecognized Material Template: WOOL_TEMPLATE
MAMMOTH:Unrecognized Creature Token: STATE_NAME
MAMMOTH:Unrecognized Creature Token: STATE_ADJ
MAMMOTH:Unrecognized Creature Token: YARN

@melelconquistador it's back, it goes down as part of the normal behavior for any time i update it because steam wants to uhhh verify all the files or something IDK. Instead of it being down for 5 minutes like we'd expect, MVC usually goes down for ~12 hours haha

Why's Ryno's mod page down? Anyone know why?

I defer to droseran, but if you created a custom tree growth material for your trees that was just a copy of vanilla tree materials that would increase compatibility with any mod that alters vanilla tree growth material.

It's just a compatibility issue since Advanced Agriculture changes the tree growth materials to fix issues in how the items work in stockpiles and on embark/trade with civilizations that have access to them. The way you're doing it is correct for vanilla Dwarf Fortress trees.

when you say "correct tree material" does this mean ive done something wrong that i can fix, or is this purely just a compatibility type thing

You're the best!!!
