Blocked in Dragon Spire

I have finished this level but i didn't get yet to shurugon castle so i still don't have the things and words needed.

But i can't go out!!! when i come back to the first entry, and i use the lever, the outside door doesn't open ! (bug?)

Where can i go to get out of the caves and go to shurugon castle ?

help please

You need to deal with the big dragon before you can get the sword and exit the caves. Once you do exit, if you want to wander back towards the castle, you need to climb or jump down the wall as there's no real pathway leading down to that area. Following the pathway to the left along the castle wall leads you to another path altogether.

There is a silly problem with the front door to the dragonspire and you just found it.

If you stand in front of the lever when you pull it your party blocks the door and it doesn't open. Make sure you are standing as far from the door as you can when you pull it and it should open. Took me ages to figure this one.

GREAT BRUNO
YOU've got a little problem...
You have to deal with the dragon but before you have to go the Shurgeon castle. So Maybe the solution REVERT GAME. Do the Castle and see what you have missing...GOODLUCK

I could only get back out by standing "around the corner" from the lever before activating it. Anywhere else, I would get a message about "crushing damage" as the door apparently hit me, although it didn't appear to move.
