Boss Spawning in Base

How do we prevent the boss from spawning inside someone's base if they build near that area?

I had a player that kept getting killed in their base by the boss spawning inside.

Hello, which area is near?
This boss have custom or random spawn?

It was a custom spawn point for the boss.

Sorry, but then I think the only correct and best solution to this situation would be to install custom positions only where construction is prohibited, or use random spawn...

Can't you make it avoid TC radius or something?

At the moment, based on your description, I have almost no idea about your situation. The only situation I can assume is that, for example, you set up a custom position for the Boss in an open field, then a player build there, and the Boss, accordingly, despite the player's building, continues to spawn in this place, but why do you need a custom position there, if you can use a random position in the same way?
Custom positions are needed just so that, no matter what, NPCs appear in them.

If you still insist on some fixes, please explain your situation in more detail, attach a video or screenshots.
