Bugs

 * If Larry disappears after being sent to a settlement, he may end up in the "Quick test cell" limbo which is a very small test room, with other random NPC such as Scribe, Ness, Mr. Gutsy, etc. Ness will be hostile and may possibly kill any non-essential NPC. If he disappears, use to find him and other NPC.
 * Some Level 4 Merchants won't travel to or stay at your settlement after being assigned there. Solution: 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.
 * It is likely that Larry will never appear at a settlement once hired, he cannot be assigned any task yet still takes up a population slot. . It also becomes impossible to reach 100 happiness at that settlement with an unassigned person.
 * It is possible to assign him to tasks by using the console: target him with, enter and , then fast travel to a remote location and return, after that you will be able to command him using the workshop menu.
 * Another solution is to head to the settlement where he is wanted, type in the console to select Larry, then, , and finally.
