Silus said: I made an update to my attack, and suddenly the ammo API function stopped working entirely. I've deleted the attack and created a new one. It seems like if there's a mistake in the Attacher that it's possible to screw up the entire sheet. Has anyone else experienced this? In case I'm doing something obviously wrong, below is a screenshot of the attack. Full content of the attacher: !ammo @{character_id} repeating_attack_@{id}_ammo [[[[-@{usage}]]*{[[@{full_attack_query}*@{full_attack_number}]]d1,[[1]]d1}kh1]] @{ammo_type} I believe i have figured out the issue. If you do not have the Ammo API script installed, then adding just the script into the attacher will not have the message pop up.
