Since update, we are widely use new features and functions, which are very similar to typical maphack options. Thanks to lack of Garena's support, newest maps pretty surely will cause desync or fatal errors mid-game or so. To avoid this we recommend you to switch to Ranked Gaming Client or patch your Garena with GarenaTotal hack.
Be aware it's up to you to decide if you want to install Garena Total software. We have no responsibility whatsoever for it's content, actions of behavior. This tool provides disabled Garena protection, and that's only reason we ever could recommend it. It may have drawbacks, let us know if you actually know any of them.
If you don't want to risk, you should join to Ranked Gaming.
