1: I assume you mean the EMP on the car. Yea I think currently, when the car is over, it still affects you for a short time. I see how that doesnt exactly seem right. Because player clones are not enabled (meaning you cannot be shot or hit by EMP directly) it gives the nade a little extra. Consider it feedback from a little car with a video link to you that went phft that overloaded your electronics. Some people call this a bug, others call it a 'feature'. However I suppose I should add hardwired so if you have that the feedback wont affect you.
2: I could but that little change requires adding another custom version of a menu item. There is very little room for adding custom menus and that is hardly worth it. Add too many and the server crashes. But perhaps there is a graphical thing I can do... using existing materials... that tells people what happened. I am open to ideas.
Long term, for the next update, is maybe use the same ones for 'defrosting' but I have to be careful there are no conflicts. If you are standing next to an explosive, with the message, but start defrosting someone what should that text element do? What should it do when you stop defrosting? All those little things have to be accounted for or you get wierdness or script errors. Parts of that requires rebuilding the mod so I cant do it on the current one with script changes.
