I have only the basic journeys in the dark RTL set. After getting through the first room, it asked for tiles 88 and 93, which I don't have. I double checked that my collection is correct.

I too am having this issue. I checked the app settings, and I made sure no expansionsuch were marked. All that my RtL app has programed in is the base set, and the 6 core lieutenant packs.

I guess it's a good thing I don't have time to try it out for a bit.

And it's fixed! Patch out now:

1.2.1 - Delve: Fixed issue causing Chains that Rust stages to appear when not in collection.
