UpdatePositionData()

UpdatePositionData() … where is this??? Renamed???

Trying to solve this below on an older modified core

https://github.com/TrinityCore/TrinityCore/issues/20028

Would like to be able to apply the simple patch from @Treeston here:
https://github.com/TrinityCore/TrinityCore/commit/28b3469e89f89a8c87fad06bad27800939abf0f5

the above patch adds the line…
UpdatePositionData();
…to 3 files.

Trying to compile gives an error eg “no found” UpdatePositionData()
Have tried a search of the code… I cant find the routine either!

What am I missing?
This is likely to be something I’ve done or messed up.
Thought I would try here first.

Core source: https://github.com/conan513/SingleCore_TC
npcbots branch

Its been pointed out that this routine UpdatePositionData() must be in one of the newer cores but really cant find it… a friendly link out to repo with this inside would rly help ty.
