Invisible creatures

Well i am trying to Vac/Speed/NoAgro hacking
with unpacking the pack files and edit the files creatures/ai info
i can change the names etc and pack it again this works perfectly

but when i log in to dekaron. i see the names
they aint moving and i don't see the creatures they are invisble
when i stand close to the creatures they just attack me but there is no way to hit them back.

now i packed the old files again but the monsters are still invisible but now the names are "Spider" "Spider larva" Etc etc

how to fix this

first of all is this on your private server or offical dekaron game?
1. if its your own private server be sure that you made backup before you edited anything, then try to restore back files from backup and go again
2. if its on official dekaron dont bother anymore cause everything that is connected with exp and etc is server sided

Its on official dekaron, thats what i tought but lot of people say it should work.
anyone know other ways to run a vac hack?
