Fugu: I'm at the point in the game where you have to collect megacredits to upgrade your castle. I got the eight from the Temple of Yak and upgraded the castle. At this point in the game, you are supposed to receive the key to the Tomb of 1000 terrors so you can collect more megacredits; this did not happen, so now the game is, as far as I can tell, unbeatable as I cannot get the master builder to give me access to the dungeon beneath the castle even though I have freed Crodo.

Is there anything I can do at this point in the game other than cheat? Returning to Newcastle does nothing and I just get the dialogue to talk to the master builder in Castle Burlock and my castle is unupgraded. It would seem that the real bug is that the game ate my megacredits when I gave them to the master builder.

EDIT: So I rested inside my castle and the stone of 1000 terrors appeared in my inventory with no dialogue, but the town is still unupgraded. I guess there are still enough megacredits in the game for me to do the remaining upgrades but there's still something fishy going on here.
