Buying/Selling Items Taking Long Time [PI] GIF

[ProLikeHamma 0]

Okay so basically i'm have the issue were when i buy a large amount of items from a shop like lets say for example 5k runes or even 1k, It doesn't show up in the inventory and lags and when you exit the shop it all slowly adds up in your inventory and you are unable to move until it finishes. This is the same for selling. Hopefully that's enough to explain for yous to know what I'm talking about. If anyone knows how to fix it please help
