Just wanted to say I'm experiencing the same problem, deployment screen messed up as well.
During work hours, prisoners assigned to a working space just stand there, while others can move freely. As soon as I cleared my regime, all prisoners started to move again, but the guards are still stuck.
Tried loading the prison again in a12, everything worked fine expect my 100k periferal wall was gone
In a13, the deployment issue seems to affect ability to search cell blocks as well. Nothing happens, I guess because there is no block defined. Single cell search does work somehow.
I tried laying out a new building to see if it would be ok in the deployment screen, no dice.
If anyone has any idea about how to fix the f'ed up deployment and zones definitions, please enlighten me.
EDIT: oh and starting from scratch resolves the issue, I tried, but it would be a real pain having to rebuild this prison.
