BotReSpawn 1.4.1

I don't think so, no.
I think your only options would be to set Stationary true which, of course, means they can't move,
or maybe create your dungeons as part of the map in RustEdit, so that navmesh gets baked on to them?

I have no idea if that's actually feasible or how it would be done, though.

Is there anything we can do about invincible bots?

Give me some context.
The only deliberate invincibility in BotReSpawn (off the top of my head) is the optional invincible whilst parachuting option.

If you're finding they're all invincible then you've probably got the server in PVE mode, or some damage controlling plugin is protecting them.

Have to refer to the previous answer, I'm afraid.
I think it has to be server pve enabled, or a plugin managing damage.

There are settings for invincibility under certain circumstances, like whilst parachuting, or immune from damage beyond, or friendly fire,
but nothing that would make them permanently invincible.

My advice would be to type 'pve' into server console and make sure it's false.
If it is false then unload all plugins then load only Kits and BotReSpawn and test.

oxide.unload *

oxide.load Kits

oxide.load BotReSpawn

I'd bet it's some kind of zone based pve/pvp rule or something,
but doing the above will prove.
