CharSetAttr API issue with changing the Exhaustion Level on the 5e OGL

When I try and change the exhaustion level of a character using the CharSetAttr API the effects part bugs out and says "??? No Effect" when there should be. If I manually change it then it is fine. To fully fixed it then I have to take the exhaustion level down to 0 then back up to the number that it should be, that kind of defeats the purpose of using the API for that.

The D&D 5th Edition by Roll20 Sheet has a number of oddities like that, unfortunately. I'd like to track exhaustion properly, too.

Ran into the same issue, so I no longer use the OGL sheet's exhaustion tracking for exhaustion. Instead, I make sure the first character resource on a given sheet is labelled Exhaustion, and my exhaustion macros adjust that resource. (this trick borrowed and adapted from Poltergeisha's Roll20 Like A Boss ).
