I just installed UFilter on my sever howerver when I type a censored message, it duplicates into the censored message AND the same message without censoring. Im not sure what could be causing this, was wondering if youve encountered this before?

Sounds like you have another plugin sending as well, otherwise may have already fixed this locally.

Wulf ,I noticed in all the posts related to this issue you are saying the same thing, but it's just not true. I have no secondary chat plugins, pure vanilla setup plus this plugin and it is duping the chat as everyone else is saying.  

Fixed in the latest build, sorry for the delay!
