Practice Range: In area 33 of the fortress level of The Sunless Citadel (pg 22), it states that if things go badly, one of the goblins "attempts to warn the goblin warriors in area 39." The problem is, there are no goblin warriors in area 39.Underdark Access: In area 23 of the fortress level of The Sunless Citadel (pg 19), the read-aloud text incorrectly puts the Underdark tunnel on the east side of the room.This check should actually be for the mechanical lock. Dragon Door Lock: The description of the locked door in area 6 on the fortress level of The Sunless Citadel (pg 14) indicates that one can make a Dex check with thieves' tools to bypass the magical lock.Also the description of the age of the rope conflicts with the age of the camp fires, tracks, and introductory summary. Ravine: The description of the ravine conflicts with the description of the ledge and doesn't match the map very well.

DM's might prefer to enlarge the maps, or allow their giants to be Large, given it's assumed that the Giants built their own lairs hence would size them appropriately. This is a hang-over from the AD&D days, when most giants were Large not Huge the 5e maps have not been re-sized.

Considering that much of what was on the PotA list made it into that adventure's official errata, it's possible the same thing might happen here. Much like I did with Princes of the Apocalypse, I'm working on compiling a list of all the major and minor errors and discrepancies in Tales from the Yawning Portal.
