I’m using version 4.26, with the latest version of the plugin available for that engine version. I haven’t been able to pinpoint exactly what it is that causes the issue, but it seems more likely to occur when I duplicate a dialogue class. When I change the dialogue in the duplicated class, the changes (sometimes) apply to the original as well. So far, I haven’t encountered this issue when creating a new dialogue class for each dialogue, so I’ll stick to doing that for now. I’ve been using the plugin for just over two weeks and have experienced this problem around 10 times or so. I apologise, I can’t get more specific than that as I randomly work on the dialogue whilst doing other work.
