so, how?
To get a bot to hold still is literally two lines of event.
Onbotspawn>bot>setwanderdistance>stayatspawn (or try a parameter set to zero.)
Onbotspawn>bot>setidlebahavior>OFF
This will make a bot completely inactive unless ordered to do otherwise. To make things even easier, there is a
"default bot" for when you don't even want to put in those two lines of event.
