@Nanao-kun 's bug, but I feel like someone had to begin posting bugs here :b

The bug is:
Blockers added by TBM do not enable drawing of appropriate techs to remove them. Should be easy enough to fix by including the blocker IDs in each of the tech's any_owned_planets

EDIT

Some more bug I've encountered:
- The colonist job doesn't get any bonuses from blockers
- Dangerous Wildlife grants only a single Hunter job space
