1 Person for less than half a day too, which probably cost him more time because he had level 0 Expel Undead and no Phantom kit when I mentioned it.
This is where you really let yourself down, you make great servers and no one can question your ability to code as its amazing.
But you never seen to nip issues in the bud and tackle them head on. Instead its a case of sweep it under the carpet and keep calm and carry on.
All it does it set a precedent for future exploiters that you wont act. If the guy had left observer on it would be clear he had just stumbled upon it by chance, by turning observer OFF and not reporting it (take into account Pokerface made two threads this morning on LOMCN so could easily have either PMed you here, mailed you in game or wrote a thread themselves) they were deliberately trying to exploit a bug from the patch and by doing nothing you've kinda opened the flood gates to -exploit all you want, because its never going to have a negative impact on you as even if the exploit is later discovered and rectified those exploiting will not be punished- which was even more evident from the gold botting / selling that was going on.
I'm not asking for you to whack out the ban hammer and to go crazy and be a wrathful or vengeful GM, but sometimes I have to question your choices. You'll happily hand out chat bans in game for those saying anything directly negative towards you or the server but take the softly softly approach on everything else including exploits.
