If I chop down a colored Autumn Woods Tree I get Leaf blocks instead of saplings
I'm playing the the latest fabric version of your mod.

Bug reproduced, it will be fixed shortly. Due to a botched copy / paste and find + replace: https://github.com/TerraformersMC/Traverse/blob/1.14.4/src/main/resources/data/traverse/loot_tables/blocks/orange_autumnal_leaves.json#L24

(predicate got changed to porangeicate which breaks everything)

All works fine now.
Thank you for the fast response

You're welcome! Thanks for reporting :)

Fixed in 2.0.4 (b140ec8)
