How do you open a mansion in the level builder?

[brell]

Thanks Rob but I will check my mansions and I think it is best that builders check their own productions before going Lion. However, since some builders do not seem to be around anymore, we might have to check their mansions and it is good if you and hopefully more players can do the checking. We have a lot of custom mansions that must be checked to see whether they work correctly with the HD version and this must be done by players/builders that are running OS 10.6.x or older.

One issue I have found is described here. Another one is in

Back to Square One

: When I press the return key to read signs I get a blank sign and the game stops with this message:

File: Sprite.c
Function: SWRemoveSpriteFromAnimation
Line: 42

This is very strange since all signs work correctly in

The Pirate Invasion

, which has a LOT of signs.
