It seems that you have renamed the NPC from "Poring Event Claimer" to "Poring Prize Claimer".
To fix it you will need to rename the npc back to "Poring Event Claimer" again or rename all "Poring Event Claimer" to "Poring Prize Claimer" (press ctrl+h on your notepad).
It gives a warning for spamming. I just made a warning so that players are still able to use it after, but if spammed, you can give them a Warning it and / or jail or ban them. ~
There are already moderators for that; Admins, Global Mods, Scripting Mods, etc..And I agree that simple scripts shouldn't be allowed, but since there aren't much scripts right now, anything would help for starters.
I was actually wrong with the above idea ^, i tested the same thing with both methods and it seems to work fine now. I'm not sure what exactly was going on, but it seems to work properly.
Wow this will go a long way. Excellent idea of remaking more modern day/efficient GRF editors with features that everyone wants! The edit/save on the spot GRF will be sooooo much better. Man do I hate extracting and repacking the whole god dang thing everytime I make a slight edit. A neat function I would recommend with the GRF sharper is encryption & decrypting feature. So for those that lets say encrypt a GRF and dont have the original one and cant decrypt it, it would be awesome if both functions are possible in this editor itself.
+1 To an excellent start. =)
