Hi,
did u do any tests on ups impact?
is there an option to switch between logistic / construction / personal bots?

They are always on: White for construction bots (personal bots are also construction), black for logistic bots.

UPS by my factory was same.

Nice to know, I'll certainly give it a try.
Enough of these pesky bots leaving my personnal roboport to do random stuff then struggling to come back when I lay a blueprint (because of course my avaible robots aren't the ones chosen to build the blueprint, no) ; without knowing where they are !

thats why i asked if the personal bots could be distinct to the normal construction bots ;)

It's impossible to make new, but same bots and use them only as personal construction bots. With new color, why not.

One of the (F4) DEBUG menu options (show-player-robots) will draw a line from you to your personal bots. That way you can see where you left a bot on the other side of the map.
