I've seen two other posts about this on the forum but I will try and go into a bit more detail. I purchased the Lost Mine of Phandelver campaign and was going to start it tonight.&nbsp; In doing my due diligence as a first time DM I was testing things out to make sure we were good to go and I found that some of the character sheets in the "Bestiary" folder aren't rolling for attack properly and a message "No attribute was found for @{Stirge|attack_display_flag}" comes up.&nbsp; Others are working fine. I've attached a screenshot showing two rolls one that didn't work and one that worked fine.&nbsp; Thanks in advance for any help. Also here are some links to other threads about this and on that might be related that was already resolved.
