Let's try one more thing before we move onto more technical troubleshooting. Mike D. , and darksaibod please work together to try the following: Both Mike D. , and darksaibod : please copy and paste @{Yuuki Hanamura|Stealth-ability}, @{Yuuki Hanamura|Stealth-ranks} and @{Yuuki Hanamura|Stealth-other} into the text chat. Let me know what each of those returns. From the Journal tab of the Sidebar, open Yuuki Hanamura's Character Window . Switch to the Attributes & Abilities Tab . Look for an Attribute named "Stealth-ability". Delete it if it exists. Do the same for "Stealth-ranks" and "Stealth-other". All information for Stealth should be reset on the Character Sheet; have Mike D. fill it out again. Repeat step 1. For Mike D. : additionally test @{Yuuki Hanamura|Stealth} again. If none of the above works, we'll work through the guide to Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions and anti-virus programs. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) I'm sorry that this is such a long process, but the information you're providing will help others in the future who encounters issues like this. Thank you.
