Dont disageee, actually I think it would be most wise to diasble the ability to syringe team mates before death as it contradicts the game mechanic of using a revive to avoid a gib. Or at least half or 3rd it.
Good move, as long as it doesnt get abused. Some folk are a bit unhinged.
Maybe set up a new level, like a hall monitor that way u can put trusted ppl in it, and remove etc. And give that level the !kick idk.
prolly u have some missing 32b libs (dependancies)
ls -al /usr/lib/x86_64-linux-gnu/libSDL2-2.0.so : /usr/lib/x86_64-linux-gnu/libSDL2-2.0.so -> libSDL2-2.0.so.0
