Not a Bug. This is more like feature request (restore fluid mixing!)

(weak ref: 68074)

bots cannot revive ghost pipe, but you get alert:

To investigate is why number of alerts in your video does not increate from 2 to 3 (however there is alert icon on map)

As boskid says, this is currently working as intended because ghosts are not part of the fluid mixing checks. So, the check only kicks in when the bot attempts to place the pipe and produces the alert posted by boskid.
