Spawned Dimensional Doors have Stopped Working

[RangerGD]

I just noticed that all of dimensional doors to pocket dimensions that have spawned in the world have stopped working (Tekkit 1.2.8e).  I am still able to place rifts and warp doors and those work fine.  The warp doors are in place for any of the pocket dimensions that I visited from the overworld, but they no longer work.  I can open the door, but when I try to walk through it, it immediately closes on me.  Also the dimension/warp animation is not showing up.  Any of the naturally occurring doors don't have the warp door at all.  Just the column of stone.  Any ideas?
