Villager with wrong jab accepts wrong working station.

What I expected to happen was...:
a cured (liberian)villager should accept a lectern as his working station

What actually happened was...:
when I placed down the lectern nothing happened but the moment i placed down a smoker he accepted it(visible throu the particles) and another villager with no job couldnt work there

Steps to Reproduce:
1. Give a villager a lectern as a working station(Level him up to level 2)

2. Cure him 3 times

3.give him a smoker 

4.Fixed after restarting
