Dupes lose skills after being accepted for education

PS: After finishing the "Apprentice Digger" training, Marie can dig again

Then she was sent to Gofer training to gain some strength.

Oh, no! Her digging skill is greatly underappreciated again - only 3 points!

Look how she frowned after taking the cap

After a while, Marie has completed the "Gofer" training.

Unfortunately, her strength is still 2 and her digging 3.

At least her fitness did improve to 5.

Let's see what Courier training can do for her.

Few cycles later, Abe has finished Gofer training and was about to start Courier training.
Interesting, at that point Marie's digging skill was again 13!
