Looks like this one was more or less blind alert. The problem existed
on older versions but it has been fixed. Me and many other people have
played in the arena since - no "locked players" whatsoever.
Maybe the guys have used paralyzation and then thought the old bug
is still present. If not, the bug must be in the general dying code because
the arena (battleground) uses the exact same functions in the same order
and all.

This is simply not true. The levers are connected to the gates
*in front of* the players there. Having no effect on the opponent's gate.

      If that player goes through the gate, he gets teleported to the arena -

According to what I said above, it is impossible to move on without
pulling the lever.

      End result?  Two stuck players.
     
     
Unless I greatly misunderstood you, what you describe cannot happen.
I have the feeling that you looked at the map via editor, but didn't
actually try it out.

There is a break-away wall to get in/out when the spikes are closed. Should
be quite easy to spot I thought.

Could you verify the bug? I couldn't, yet I tried many times. I believe it's
unlikely that it has to do with movers. They work fine in all other places,
so why not in this case?


Again, referring to your statement above:

      trapped/screwed up.
     
     
That is an incredible tricky mechanism on the arena map. I made it as
secure as possible. But when players try to break it intenionally, there
will always be a possibility to get stuck.
To my knowing, there are two ways:
1) After both players stepped on the teleporters, one jumps off exactly
   in the second before it is activated. You need hell of a timing to do
   that, but it is possible.
2) One player bails out with word of recall during the enter-mechanism.
   (And the other player doesn't have WoR).
   I can't insert no_spell objects, since then the players can't escape
   when it is really neccessary (either due to 1) or server crash).

I have seen many people play in the arena, never seen anyone getting
trapped.
Everybody is welcomed to propose solutions to get rid of either 1) or 2).
Otherwise we have the choice to either accept the risk or remove the whole
map.
