I found one map change that caused my client to crash. I have the latest release (though since you don't include the build version into the exe's details, I can't give you the exact build number).
When I walk through this map change:

My client crashes with the following error:

P.s. It might be helpful to include the build version into the exe's details. Then someone could give you an exact build number. I don't memorize the build of my programs. It's a pretty common practice to include it, not have it listed as 1.0.0.0
Edit: poool helped me test. He is using linux, a build of unbutu called mint. no crash for him.
I continue to crash (at least 7 tests so far).
If I chose the ignore option, I go though, can chat and play for a bit... but if I leave the area, I crash with no pop-up and no options. just a straight crash.
Edit2: A windows player helped me check: salvo using vista x86 didn't crash.
So not sure where the issue is.
