Mastery badge is missing in tech tree

[Tomasso]

Dear Aslain,

first, love your mod pack, really appreciate all the effort you do.

My problem is that the mastery badge in the tech tree isn’t working anymore. Wonder if I set something wrong or what, so can we wait it to get solved?

Thx in advance.

I think it's a bug in XVM, since it's enabled in the config but not visible in the tech-tree.

Do you have any info about whether they intend to fix it?
