Hello Shaiya Community, since I didn't find a fix for it here so I decided to post the fix with the offsets required.
So, Vet Manager has double-side level check which means both game.exe and ps_game.exe check your level before letting you get the points and death benefits.
I tried it on ps_game.exe which comes with @'s files and an unknown game.exe. I will post them here too.
Offsets for game.exe:
0048DAAF
005088F0
and ps_game
00469A19
00469A40
00469A67
Note that the ps_game.exe is ep 4.5.
Use OllyDbg to edit it. Change 10(which is 16 in hex) at the end with a hex value of your wish.
All the best.
