Hi, I'm getting this sort of error, when rolling damage from the Player side of the app:
Attachment 42841
Attachment 42842
That's what the coding on an effect for Mace of Smiting was. And when I initially did this on DM side, it worked just fine. It works on Player end exactly until it actually crits.
Now, I've been trying to use plenty of extensions, and with some trial and error it seems that it has something to do with Advanced Effects extension, when I tried to make some things like automated Mace of Smiting that would automatically put an effect on character that would detect type of target and roll higher critical damage on natural 20.
Since when I turn it off and paste the effect formula as normal effect without Advanced effects, it seems to be working normally.
Other than Nat20, I'm using DruidWildshape, 5e Enhancer, and Constitutional Amendments.
