Rejected [Workers]Can't be deleted/send to work=skill prob.

Bug Name:

[Workers]Can't be deleted/send to work=skill prob.​

Bug Description:

From what i can guess there is a bug with one worker learning the same skill 2 times causing him to glitch out.
Already have 2 (one green goblin and green giant), both are broken and they both have one skill that is learned multiple times. Can't use or delete them, it says that hes working (...).

Flax Farming sub-node at Moretti plantation is broken, cant send worker there, i'm guessing one of those workers mentioned above have something to do with it.​

How to reproduce/proof:

Indeed!​
