same happens when you hook the rope to a crate and then pick it.

the only obvious fix would be to let the rope vanish in these situations which is not wanted right now.

there was a thread about it but i can't find it right now. i think it'll stay this way.

That's due to the way the rope works right now. It could be considered as a bug but it's not like it happens every second game or so (-> not THAT important like some other bugs and caveats right now). Hedgewars doesn't use any complex physics engine - it might need some huge rewrites to get this working (haven't taken any look at that part of the code).

I don't see it that complex. Just that rope shouldn't hook into either crates or hogs and we have half the problem solved.

As for explosives, just like a hog gets his turn end if an explosion reach him, it should be the same for ropes, instead of ending turn, rope get wasted.

Of course, I also haven't seen how the code is written but I imagine it wouldn't be that complex but I could be wrong of course.

It would be easy to make the rope disconnect in those situations but I think that would make the game less fun. Realism is overrated.
