Kraynic said: How are you changing the attribute? If you are using the api, you might want to post the command you are using. The command used may be telling it to create the attribute and value instead of simply changing the value of an existing attribute. I use the settings of the D&D OGL Sheet, the "Apply default settings" feature as well as this script: <a href="https://app.roll20.net/forum/permalink/9822005/" rel="nofollow">https://app.roll20.net/forum/permalink/9822005/</a> Not 100% sure how exactly each influences the sheets specifically, but I'm confident the "Apply Default Settings" featue screwed me over big time, since the issues appear right after I used that. However I could not recreate that so far ... or if I did I coulnld't spot the change ... its ridiculously difficult to tell. Some of the sheets reached over 30 of those duplicates ... manually changing the setting from the sheet seems to be fine, I guess? There are sheets afflicted that I never touched since starting the module. the script appears to do nothing at all??? P.S. I don't expect a fix. Tech support is aware and they can't fix it. But here's hoping someone might have an idea after all ...
