The Land Claim Block (LCB) is now used in both multiplayer and singleplayer. Most notably, user-crafted workstations (workbenches, cement mixers, forges, etc) need to be within the realm of a placed LCB in order to be removed. Hitting it with a wrench or other tool will just destroy it.
The question: If I put multiple LCBs down (multiple bases, etc), I know that only the most recent LCB placed affects the workstations (I've already experienced this and had to put down a new LCB in order to move my forges to another location) but if I leave LCBs in place in an old base, placing a new one elsewhere, will the original LCB prevent zombie spawns in that area?
TL;DR: I'm building an underground tunnel system between parts of my base, which spans more than the 41x41 space that a single LCB affects, so if I put multiple LCBs down in various areas, can I effectively prevent all zombie spawning inside my bases?
