Solved Something seems wrong

Whenever this guy logs into my server it doesn't take long for this error:

This goes on and on for thousands of lines.

Notice in the middle it said:

2012-09-27 17:30:04 [INFO] [NoCheatPlus] (NAME REMOVED) failed FastClick: tried to move items in his inventory too quickly. VL 669.

I removed the name because if no harm then I do not want to tarnish his name.

However, I get that NCP alert a lot with him and at the same time that severe error.

I still use Bookworm because it works fine for my quests I have on my server. This error has never come up and doesn't come up when anyone else is messing around. However, the "inventory too quickly" report I get and the error at the same time makes me wonder what is going on.

Is there anyone in the know, who can explain this?

 

Code:

2012-09-27 17:30:04 [INFO] [NoCheatPlus] (NAME REMOVED) failed FastClick: tried to move items in his inventory too quickly. VL 669.

Means he is using a mod to move items in his inventory.

The other error i would report to bookworm.

Well it only happens with him.
Going to speak with him about it.

Thx for the help.
