Hello all, I just had a quick question regarding Volo's Guide to Monsters for 5e D&D. In the Charactermancer, I am seeing a few different entried listed as both (Volo's) and (VG1.) I checked the Wiki and it states that the Source-ID is meant to indicate a new physical printing of the book. If that is so, why am I seeing both listed? Shouldn't I only see the newest printing? Or am I misunderstanding? Thanks!
