Because I love this mod, and the effort put into it, I will invariably side with the dev team on the opinions of a larger player cap. A lot of the admins hosting these servers probably, in my opinion, endorse gigantic 16+ player mashfests with random weapons because, hey, that stuff gets freaking rowdy. This mod hasn't even been out a full week and people are complaining about things that aren't even a bug, they are more innocent oversights by people administrating servers who probably loved the original as much as we do.
If the players new to this iteration of the mod would give it some time, most of the people hosting the large servers will realize that 16 player complex is a bad idea, because the map isn't big enough to accomodate 20 Boris' and Mishkins running around and that will cause players to telefrag. The servers with large player limits need to play more levels like Cradle, Runway, Egyptian, Casino et cetera.
I would advise anyone making their own maps to space them out to accomodate the max 32 player limits and put a minimum of probably 20 or 25 info_player_deathmatch entities to prevent the suicide incidents.
As for not knowing what weapon you're using, turn fast switch off and use your mousewheel or 1-5 to check. Or, better yet, try binding keys to certain weapons so you can always be sure you have the one you want out.
