Simple answer really, you must Ed(i)t the tomb walls.
Left wall is conn:0x21222122
right is conn:0x11221122
up is conn:0x22212221
down is conn:0x22212221
UR Corner is conn:0x22222121
LR Corner is conn:0x21222221
LL Corner is conn:0x21212222
UL Corner is conn:0x22212122
Waste of time, really.
Also, for your second question, I need to see a screenshot of the map. Don't add realm portals, loot bags, and you need to add some properties to the portals.
