#1: i have spent some time in agility arena in karamja and i have noticed one thing - that when u complete a couple obsticles u are not able to walk at all u are only able to go back the same way u came and second is you seriously need to improve  its graphics because some obsticles are just standing on tin air.
#2: "duel arena" this bug has been in duel arena for some time. when some players are not able to challange a payer or accept player challange. i know some of you might say "just relog and everything will be alright" but its so annoying when u just want to duel with someone and u have to relog every time you do this. that's all for now
