After setup time ends my game crashes like i have to leave the server as it ends so i can come back this is a problem if i have to sub engi or medic. Don't know what's the problem any thoughts?
It's most likely a problem with your HUD. Try installing the latest version of your HUD, unless you're making your own of course.
It's the stopwatch mode. I remember having this problem with Doodle hud. Update your hud, and if it still crashes, then that hud doesn't work with stopwatch mode, so you'll have to find a new one.
If you really like your HUD, you could always find a HUD with a good stopwatch that doesn't need new fonts, and just add it to your UI folder (or make an exception if you have an updater). I've done that with a few HUDs that I've used, transferring old pieces from other HUDs to new ones (my current E.V.E HUD has a modified Brosel class select that I've carried over multiple HUDs). As long as you don't need new fonts and are okay with it possibly looking out of place, using a different stopwatch should be a passable solution.
EDIT: I forgot to point out that you should also copy the HudLayout values for it, otherwise it won't show up.
