Rash said: Kyle G. said: The script will find the ID for the item if none is provided in the ammo section of the attack. If you are removing and readding the item Arrows to the character sheet, this will invalidate the ammo sections that use the item since the new Arrows item will have a new ID. If you remove the ID from the ammo section for the attack (simply make this section "Arrows") and then click the attack button, this should fix the problem and update the ID for this ammo section. Let me know if it still doesn't work. Using a new Shortbow and a new arrow item, and addin the ammo section with "Arrows" and then attacking gives me nothing. ps: my HotDQ is saying "Compendium sharing has been removed from this game." will this have an effect as a player? Just for sanity sack, is the arrow item's name the same as the name used in the ammo section? Secondly, is there an error being in the API scripts page that requires you to reset the API scripts? The creator of the game may have to check this if you do not have GM control. As for the Compendium error, I don't think that would have an impact on the script. It should simply mean that you cannot drag PHB, VGtM, or MM material from the compendium into the game, but the SRD material should still be there if the creator has the game set to use the Compendium. If the entire Compendium has been removed, it simply means that you cannot drag-and-drop at all, but the API script should still be able to work if it did not crash already.
