I will try to make an update of all this if I have time, because I also work on the release of my server, as soon as I have time I will publish an Update.Any idea what I can do? Try another client? I specifically tested the same area during crashes with a copy of the with this MPQ and without it - no crashes occured without the custom MPQ so I for one think its this one. I will try to find another full client to double check.
Thank you for your work <3
