I know there are some AFAIK still unresolved Roll20 issues between API and sheetworkers, but I'm not sure if this is the same type of issue. Please share your ideas/advice! Sheet: Pathfinder Second Edition by Roll20 The sheet allows you to specify how an items quantity is calculated into the overall bulk. For example, 10 arrows have a bulk of L (treated as 0.1, or 0.01 per arrow), so on the sheet you can set the bulk as L for every 10 arrows instead of for every 1 arrow. If I use either the Ammo script or ChatSetAttr to adjust the quantity of any inventory item, the total bulk changes to calculate every single arrow as L bulk instead of every 10 arrows as L bulk. Here's how this looks: below I have an inventory with 100 arrows (1 bulk) and a longbow (2 bulk) for a total of 3 bulk. If I use Ammo or ChatSetAttr to change the quantity of the arrows, the total bulk changes from 3 to 12, treating each arrow as L bulk. I saw someone post recently about hyphenated repeating sections causing issues with how the API interacts with repeating sections ( the post is gone now see below; thanks Andreas!). The section that arrows are in here is repeating_items-worn. Anyone have ideas about whether this is a sheet issue or a script issue? Thoughts on how to fix?
