I am testing the Pathfinder sheet in production server, and when I go to the ability scores (first tab 2nd section) and enter numbers in the Strength row, &nbsp;"Enhance" or &nbsp;"Misc" column, sometimes it updates and sometimes not. I turned debugging on ,and found the event that was firing said a sheetworker updated the field, when actually I updated it on the page. This happened &nbsp;maybe 25% of the time, and I'm not sure why. I can make it happen if I update the Enhance column, hit tab, then update misc, then tab again. if i do this a few times quickly the offending event will fire. (technically I do not have to update quickly) I also tested with empty sheets as well as filled in sheets.&nbsp; Here is the log, the line DEBUG: caught str-misc event:sheetworker when it should say "player" Triggering for change:str-misc VM29:178 &nbsp;TAS: &nbsp;Entering: eventUpdateAbilityPlayerUpdated&nbsp; VM29:178 &nbsp;DEBUG: &nbsp;caught str-misc event: sheetworker&nbsp; VM29:178 &nbsp;TAS: &nbsp;Exiting: eventUpdateAbilityPlayerUpdated&nbsp; sheetsandboxworker.js?20160926:57 Triggering for change:str-misc_max sheetsandboxworker.js?20160926:57 Triggering for change:cmd-str VM29:178 &nbsp; This happens in our normal prod campaign with the current sheet. However, here is a copy of the sheet with debug turned on.&nbsp; <a href="https://gist.github.com/plutosdad/9dd2da92a76f2cd1" rel="nofollow">https://gist.github.com/plutosdad/9dd2da92a76f2cd1</a>... line 14591&nbsp;is the event capture line that shows up in the log as above. it calls updateAbilityScore which is above it in the file, but it's the event misfire that is the issue i'm having. We have to check whether the event source is Player or Sheetworker to prevent loops. All the event handlers do it, so obviously if this is widespread it could screw up anyone's sheet that also does so.&nbsp; and here &nbsp;is a link to the test campaign:&nbsp; <a href="https://app.roll20.net/campaigns/details/1759093/a" rel="nofollow">https://app.roll20.net/campaigns/details/1759093/a</a>... That test has many empty sheets up top, but if you go down the to "PCs" folder there are filled in sheets from players.
