MUH060169 Fatal Journey (2023) [OWN]

Looks like I bought all these in a previous Humble Bundle back in Mar 2024. This time it only adds Fall of the Imperium ($28 retail) and I guess $20 would be a discount but it seems like a waste of my previous purchase. Didn't see anything on rpg.net about the line ending so I guess I'll wait for the next bundle.
