There were several small graphic glitches and so Jagex staff used to Wise Old Man to fix them. It appeared that they coded the character of this NPC to “watch over” the glitches and make sure they didn’t happen again. One example was in world 82, where many people were able to walk on the water by Catherby fishing spots. Mod Ash soon patched up the problem and stuck the Wise Old Man there and made him run some code to fetch stuck people out of the water. There were also a few hidden system updates were Jagex quickly fixed the bugs and put the Wise Old Man back in Draynor.
In addition to the runescape gold glitches stated above, there are also quite a few of unusual things someone can do while in a player owned house. For example, there is one glitch where a player can eat quickly while sitting down and be able to move their character in the seat itself! There are also other house glitches where one can attack someone else in a dungeon even though player-vs-playe(runescape gold) mode is off. These bugs on Runescape are not reported to be harmful but we do not promote doing this since it can be considered Bug Abuse, which is against Rule 4 in the game buy runescape.
Nowadays, people may tell you that they can duplicate an item and make you rich. That is not possible anymore, but this Runescape glitch was in the past! Before, there was a minor bug in Jagex’s code, which a few people found out and took advantage of. This bug allowed any non-stackable item to be duplicated, which meant these people could use the identification code of expensive items and make as many as they wanted. Soon enough, the magenta partyhat moved from being the most expensive partyhat to the cheapest partyhat. The magenta partyhat moved from about 5 million gold to only 200k gold(rs glod) in a matter of days and caused a big dent in the economy. Apparently, these newly duplicated items looked exactly like the original, so Jagex couldn’t tell who had the real partyhats and who didn’t. Now to this day, the magenta partyhats are now of a darker shade and are still the cheapest partyhat because there are a lot more of them than the other partyhats.
