Observed behaviour

If you go into a Neutral Wizards home (wizard tower) and place blocks (such as dirt) without destroying any blocks.. you can avoid the wizard becoming hostile towards you for subsequently breaking blocks (by blocking his line of sight to you).

Currently, a player can puts blocks around a wizard to block line of sight, then steals everything in the structure without upsetting the wizard (breaking blocks or bookshelves, etc).

Expected behaviour

Neutral Wizards should become hostile towards you for placing/breaking blocks or accessing blocks (outside of optionally arcane workbench) in their structure, even if out of line of sight.

Steps to reproduce

1. Join a Server
2. Enter a Neutral Wizard Tower
3. Place dirt blocks around the Wizard to block line of sight
4. Break a bookcase
5. Trade with Wizard as if nothing has happened (Wizard is not hostile)
6. Break a bookcase where he can see it (Wizard becomes hostile)
