I can confirm that this cheat works for entering Cartella lab, beast mountain and such areas (not using teleports yet).
This also allows you to view the upgrade parts for blue/green mau but upgrading it isnt working.
Use CE:
1. Log on your character, search your level (4bytes)
2. Log off, search for 1
3. Log on, search for your level again
Step 2 and 3 may be not needed, depends on your luck =)
4. Log off, edit your level and then log on.
Screenshot guide:
Sometime you may not get the wanted search resaults. Then log in, start a new search.
Then you should see your new level (client sided)
Happy hunting in places where you dont belong
