I have the Perpetual Edition of Cultist Simulator, which in theory should mean that I get the Dancer DLC content for free. However, I don't seem to actually have it at the moment.

My GOG account considers me to have the Perpetual Edition DLC but not the Dancer DLC. I thought at first that I'd get the DLC content in my install directory anyway via the Perpetual Edition DLC, but that doesn't seem to be the case; I made sure that Galaxy had updated to the most recent game version, then checked for DLC_DANCER_dancer_legacy.json, and it's not there. And the answer doesn't seem to be that owning Perpetual Edition makes the Dancer DLC free via the GOG storefront, because I checked the storefront and the DLC is still listed as $3 for me.

So I'm confused; how exactly am I supposed to get the DLC content?

Update: with no intervention on my part, GOG now considers me to have the Dancer DLC, and as such I can now access the relevant content. So it seems like the issue was one of time delay, rather than of anything actually fundamentally not working.
