I have been trying to use the belt ratter to gather data for the NPC spawn selector (Which I haven't been able to get working). When I say I'd like to use 30 as my Max # of MBs, it always reverts back to 2. Any help would be appreciated.

Also, when using the anomaly hunter, the bot doesn't ID rats that scam, it always goes for Battleships first. The whole reason I am trying to belt rat is so the bot will fill out the NPC spawn selector and I can ID the rats there for the Anomaly Hunter. Ultimately I'd like to rat Drone Patrol/Hordes, but they have scamming rats, and I want the program to ID and kill them as a priority.

Anomaly hunter uses 2 bookmarks, if you activate it bot will set max bookmark numbers to 2.
NPC respawn statistics works with belt respawns only to not kill some NPC at all and level respawn quality in your system. In anomaly hunter no statistics recorded or used. Bot kills all NPC

But even when using belt hunter, the max BMs reverts to 2. Should I re-run the first run cycle to for belt hunter to get access to more bookmarks?

When you switch to belt hunter disable anomaly usage then set new max bookmark number

Is that done by disabling the anomaly bookmarking system? Are there more settings that need to be enabled?
