I noticed an issue with the Toland Patrols while farming them for Cipher Decoders a couple weeks back, and I figure you're probably the perfect person to bring it up to.
Sometimes when picking up the Toland patrol, he would not spawn and we wouldn't be able to interact with him to finish it, so we'd abandon it after a couple of minutes. It didn't happen every time, of course.
I don't know if there's some internal cooldown (My clan mate and I did Toland Patrols exclusively) but my clannie and I thought maybe someone else in the instance interacted with him or was doing another Toland Patrol in the same area so he wouldn't spawn.
Obviously I have no idea, and have no recording of it happening, but figured I'd let the man himself know. Thanks man!
