Somethings wrong with the files. Id say resub and download

Known bug. At first the faces look OK then later on they start to warp. I don't use for that reason.

It is happens when your save game is damaged. Load the previous one, without this issue. Read changelog to find out how to reduce chanse of savegames corruption (appllies to any mod).

the thing is when i started the mod for the first time it already showed the arena guy of Sarleton with that face that I almost laugh, the I started to see a pattern on others npcs(not all of them)

Yes, this may happen, on a rare occasion, during the new game initialisation. Especially when the new game is started without restarting the whole game session first (exit to desktop and then reopen Warband client).
During initialisation process heavy calculations are performed as the whole leaving world needs to be created. Not much can be done to prevent it - simply after starting the new game, open NPC list and check few random lords if they look ok. If not, reopen Warband and start new game again.

All that is captured in the 3.9.4 changelog, "NOTES" section.
