Hmmmmm, strange. What version of Timber and WP are you using? I've noticed a bunch of issues starting with WP 4.7 that I'm still catching up to

[selfagency]

4.7.1 and 1.2.1

[selfagency]

i downgraded to 4.6.2 and the issue persists

[jarednova]

Frak, well at least we know that the WP version is not the issue — thanks for giving that a spin! I'll see what I can find

[jarednova]

@selfagency good news! just a small change will fix this one...

Before

register_taxonomy('space_type', array('makerspaces'), $args);

But the name of the post type is makerspace (singular), so...

After

register_taxonomy('space_type', array('makerspace'), $args);

Same goes for projects/project — boom!
