Not sure if it was this week's update, but all of the in-sheet buttons on the 5E NPC character sheet have started giving off the "Unable to find a player or character with name: GM" error. It seems to boil down to upper case "GM" not being recognized as the "gm". To further clarify the issue, this is the code for the NPC STR save: "/w GM STR save :[[1d20 + @{npc_strength_save_mod}]] | [[1d20 + @{npc_strength_save_mod}]]" You can see that the GM in the whisper string uses upper casem changing it to lower case seemed to do the trick. "/w gm STR save :[[1d20 + @{npc_strength_save_mod}]] | [[1d20 + @{npc_strength_save_mod}]]" I basically make sheets for all monster types and it sure is handy to roll from there! ;) Hopefully the author will pick up on this soon and update all the GM to gm, should be a simple fix.
