What happened:
(Am not using anything unique, just gums and compound boon 3. Will try a fresh forge to see if this happens again)
I’ve had the same thing happen to me. So annoying.
Weird thing is, I can’t get it to do it again lol good for me, but bad for reporting it
From what I’ve seen talked about typically in that instance there is a desynch condition between the client and the server. The client predicts the outcome of the roll but once the server info catches up the actual result is displayed.
