Ok, I think this occurs when editing posts. It stores the first value in memory from the post in memory, and duplicates it when editing.
-I posted, got a crit, added d20.
-edited post to add d20 (copy pasting first dice command string)
-Encountered duplicate d20 value.
-Deleted that roll from the post (editing a second time).
-Started a new post. Got different d20 value.
Pretty sure dice roller isn't supposed to do that.
