I have been in some weird endless loop of battle, inspect area and explore area. I have't found any seals and i have literally been clicking explore area for several days several hours at a time non stop for hours at a time and racked up a lot of gold, but the seals everyone is talking about don't show up. i've met the healer lad 4x in one go and some peddler but never any seals or progress. it would be super nice to even remotely find the story line because it just isn't progressing whatsoever. is this a glitch because by now every other dungeon has had some sort of progress in a story line but not the forgotten tomb, in fact it just is randomized zombie battles and no doors, no story line or any knowledge on what to do next. what the other forums are saying hasn't even happened for me and i'm getting concerned now. i must have clicked explore over three thousand times by now and never found any notes, or break in the dungeon to tell me about the supposed seals everyone finds. all i have seen is a peddler, a healer, treasure chest and battles or investigate which sends me to a battle again.

You might wanna out this is QnA. People are more likely to see it there.
(Sorry I dont know the answer to your question)

Have you been fighting in and finishing the battles, or running from them?
