you can have this problem on ANY MP Server, not just Wasteland. Wasteland is just popular, so it's a decent example.
There is a thread in the BIS forums that has 208 pages/2000+ posts and goes on for 4 (FOUR!) years now that is talking about this very problem in Arma 2 which now has carried over to Arma 3. This is not a wasteland issue at all, it lies deeply within the RV engine and hasn't been bothered to be fixed as far as we can tell. The only responses we got from the devs were "programming is hard", "it can't be fixed" and "it's not worth our time to fix it".
