Bot can't type

All scripts that require the bot to talk don't work for me if im healing it just keeps typing eeeex and then deleting it and then typing again eeex.
But also simple things as buying supplies when the bot tries to say hi it just say hhhii then deletes it again and does it again over and over.
Any script that requires talking does this. I am using a vps had the same problem on windows server 2008 and windows server 2012.
First I thought that my vps was lagging but it isn't. This problem is occurring on tibia 11

Go to Settings (near Navigation) and increase Type Wait Time value.
