* fixed bug with player relocation while the player switches an element
* fixed bug with EM/DC style exit and EM/DC style steel exit which was
  not walkable (and did not let the player enter) when in process of
  opening, but not fully open yet (which can cause the player not being
  able to enter the exit in EM/DC style levels in time)
