HMX / Mutation Mode - Client Error 18_1 - 24_0

Hi guys,

when ever I play Mutation mode in any way, I randomly get Client Errors for quiet some time. Most of the time when I am the ACE or close to being the ACE.

Game is runny ok in any other way - ranked, snd etc. are fine so far.

I only get Client Errors when I play Mutation mode.

Error Code: 18_1 most of the time -> 
Error Code: 24_0 first time today, two games in a row.

Already reinstalled crossfire,
Streamlined my internet settings.
I have changed my NVIDIA settings to get 240fps.
That's it for changes.

Really looking forward to any help.

I have added screenshots.

Cheers.
