So, I really don't know where to ask. When I found this issue I immediately send it to Terraforged's issue tracker, but dev said that they can't do anything that will modify other mods' stuff.
The problem itself is that Terraforged uses custom tree designs for Vanilla trees - they are replaced in every vanilla biome, but Terraforged seems to not able to replace any, even vanilla structures in other biomes. Autumnity has some biomes that uses both vanilla and autumnity trees at the same time (color-spotted forests), and it looks inconsistently when there is two types/structures/designs of the same wood type.
The same probably works with other Abnormal's mods that are using vanilla and non-vanilla trees in one biome, but Autumnity has larger amount of these biomes.
So, question: Can this be solved by update, or can I solve this manually, for example with replacing tree structures in files or something like that? Thanks in advance.
