Franky H. said: I keep getting the error Possible infinite loop detected, shutting down. after installing the script Is this after installing, or after running the command? The former really shouldn't happen, just want to make sure. If the latter, I think the problem is the ridiculous amount of characters in SKT. The script will take a long time to execute if you have a lot of characters (I fear it's not really well-optimized). It's possible that roll20 thinks that it is entering an infinite loop for so many characters (it isn't, but the loop might take a long time to execute). You can try doing it in smaller batches. !setattr --sel --wtype will do it for characters representing selected tokens, or you can do ! setattr --wtype --name name1,name2,name3 for a long (but not more than 50 names long) list of character names.
