There are NPC in the game that when doing current actions or tasks will grow to longer sizes when doing said task. Once you attack the NPC, it will go back down to its original size. I noticed this issue early on when the game launched, but I'm not sure when it started happening. This is most noticeable in Folcanstand witch is located in Cent. Below you see a video where a child grows to around 10 feet tall or so while doing the action, but when attacked will go back down to normal size which is around 4 or so feet tall.
