The message shows up in chat. I'm about 90% sure I'm on the production server, as I've never actively tried to be on the Dev server. I have Token Name Number, Roll20 Audio Master, TokenMod, Group Initiative, Token Action Maker, StatusInfo, and Change Token Name. Based on you asking, I switched from Mozillia to Chrome and it works better, but still not perfect. I don't get the error message, but it also won't fill in the current HP. I don't want to roll for HP for each monster, just have the default HP set. I see that in Attributes there isn't anything filled in for HP on the character sheet where I would expect it to be, and I can't find an Attribute that lines up with it. I'm using the 5e Roll20 sheet. I was under the impression that linking hp for monsters is a bad thing because then if you change one monster’s hp (say from taking damage) then it would affect all of the tokens of that monster.
