You can still use the 2024 sheet for PCs, and for any monsters you add subsequently, but I think Vecna: Eve of Ruin likely predates the shift over. If that doesn't help, let me know and I can investigate more deeply. Hi Keith, it's running as a hybrid game and each time I drop an NPC it asks if it should open in the 2024 sheet or 2014, I've always chosen 2024 since the Monsters I am dragging and dropping are from the Monsters book from 2024, during my searches it seems this is not the first time something like this happened, there are some posts dating 5 years back that people were also facing issues when they've drag and drop the monster and it came blank. Also I noticed this may be related to the "loading" or "preparing your sheet" that happens when you drag for the first time, I think I may have closed the popup too fast and for some reason it didn't continue to load on the background and it glitches.
