The behaviour of heavy doors has changed slightly: the first character who
tries to open/close the door is not treated in a "special" way any longer.
As a consequence:
- All the characters who are trying to open/close the door are delayed,
until they give up or the door opens/closes/stops moving.
(Before the change, only the first character was delayed).
- If the first character who tried to open*close the door abandons the effort,
the other characters keep trying. (Before the change, in these circumstances,
the door stopped moving immediately)
- Characters who are hurt, bashed, paralyzed, or who move away for any reason
stop contributing to the effort.
Right now the change affects only a few doors. It will become global after
