Need help with quest

I have a problem with quest for some reason my client seem to exit everytime i even see a quest item either in my inventory or in the shop. The items drop in quest and im able to play quest but im not able to see them or my client exits. Other problem is that none of the power ups are in quest either the hp ammo or ap powerups. I believe its on client and server. I am not sure if i need a new system.mrs or another file. If there is any advice you can give me i would appreciate it.

Thanks.
