I've been having an issue for a long time where an attack will no longer function because the damage has been reduced from its dice to a singular digit. For example, a greataxe changes from 1d12 to a flat 1 or 2. There seems to be a correlation between the attack being from an inventory item ("has an attack" checkbox), but I'm not sure that's the cause. However, when an item has an attack, its properties field is sometimes filled with duplicate data. This is the data from one trouble item. Damage: 1d12,Damage Type: Slashing, Attacks: 2,Secondary Damage Type: Against non-undead, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2, Attacks: 2, Damage: 2 I've seen in this thread about this same issue that the compendiums (including paid ones) may be bugged or have badly formatted data. I have noticed this happening with items manually entered as well.
