Latest PS4 patch update

[Gerard77]

Hi, the latest patch update for PS4 caused me to lose 2 sheep pen and 1 cow pen. I have sufficient space and funds and they were actively used for some time now. I don't use seasons. I simply converted and piece of land and placed 4 cow pens, 2 sheep and 1 pig pen. This has worked well for me until this latest update.
If I try to replace them, it says terrain cannot be changed or something like that.

Any suggestions?
