Bugs

 * The dialog option to recruit her may not even be available when you meet her.
 * Some Level 4 Merchants won't travel to or stay at your settlement after being assigned there. The Level 4 Merchants seem to remain at a settlement after being assigned there after Patch 1.4.
 * After the merchant has been assigned, disable them and any other travelling companions they spawned with, such as accompanying mercenaries ("prid [ref id]", "disable"); fast travel away from the area they spawned in; then walk, don't fast travel, back to that exact same area and a different random encounter should occur, such as wild mongrels or synths; if so, re-enable the merchant ("prid [ref id]", "enable"); fast travel to your settlement; and finally, move the merchant to you ("prid [ref id]", "moveto player"). Now the merchant should stay put.
 * When asked to work for you, she may not show up where you send her. When in the settlement she was sent to, selecting her through the console, then using the commands "disable", "enable", then "moveto player" may fix this issue. The same may be true for Smiling Larry.
 * You can type 'prid 00190047' then enter to select her. Then use the moveto player and enable commands to fix.
 * For some reason she can just go away from the settlement and nothing can stop her when using moveto and enable commands. If this happens, try to wait a day after asking to join the settlement. Then use 'player.moveto 00190047' command. It should teleport you to the place where you had met her, but there will be only another encounter. After dealing with enemies(if any) use 'prid 00190047' and 'enable' commands. She will appear and travel by herself to the assigned place after some time(usual for other npcs). It seems that she becomes disabled when she should start her journey to the settlement.
 * Another workaround is the same as you can do with Ron Staples. If you meet her and she doesn't leave the cabin close to Drumlin Diner, disable her, fast travel (FAR!) away, get back to Drumlin diner and the cabin, enable her. watch out though, as if there's a random encounter like wild mongrels, synths, raiders, or super mutants, she's likely to die fast. What follows is something I would not call "AI" ... it really makes no sense, but she travels off heading for Corvega facility, passing the destroyed house where the roachking might lie in wait, turns to Jalbert brothers and proceeds to Graygarden. She then wanders further between arcjet and rocky narrows (gunner-zone), leaves Gorski's to her right and possibly messes with the two raiders at the hut overlooking Walden's Pond and eventually arrives at Abernathy's farm. Long story cut short, that's most likely the most ridiculous way to red-rocket/sanctuary, when drumlin's->concord->red-rocket is only one stone's throw away. ADDITION: the doc disappeared from Sanctuary within a week, no clue where to. -Confirmed; Doc disappeared from The Castle slightly more than a week after she was assigned there. Console commands "prid 00190047", "enable", then "moveto player" fixed the problem.
 * When summoning her to the settlement with the "moveto player" console command when she failed to show up after being recruited, she could be assigned to the surgery center, but would walk off and disappear, even after using the fixes suggested above. Attempting to summon her back with "moveto player" did nothing (she failed to appear near my character). However, using "prid 00190047" then "disable" and "enable", then finally summoning her with "moveto player" caused her to appear again, work correctly, and stay in the settlement for good afterward. It would seem that before any fixes work on her permanently, she first has to "get lost", be disabled, enabled, then summoned to your settlement and assigned.
 * Another reason why this bug occur is you recruit her to a settlement with "maximum population". Try to increase your Charisma or move one of your settler to another settlement then recruit her. You can also try this method on other "Level 4" merchants that have same problem.
 * Sometimes Doc Anderson's random encounter may spawn again after recruiting her.
