Random trashy output

[Mozitux]

Hello, when I speak to my bot using a llama model (vigogne-2-7b-instruct.Q4_0.gguf), the output is very random with no error in the debug mode.

Example of error :

`[user]: Hello!

[bot]: Shux a one can em use long Sh you for long use em Sh one you long a message one useem response can you use you a useist help use a one for a write can messageem cas Sh Sh. they help useem can. write a can you youux useist you message response long. response use canemem Sh write one they can you casem casist you cas one one you Sh youux you response Sh one help a.

I can't find the origin of the bug, can you help me?
