Please use the in-game bug report feature. And, please, first turn on logging (you can find how to do this here: https://owlcatgames.com/content/bug-report-technical
Press F11 to access the report function which will gather all the required information (screenshot, save file collected automatically). Please, specify if you use any mods.
I've seen this link posted in a few threads, but it doesn't work any more. I get a server error.
Wasn't aware of the F11 thing when playing, and when reading it now I didn't think it would work on Linux since it's a global shortkey, but it actually works (tested and the bug report UI comes up). Small thing, but there is something wonky with this dialogue tree at the start of a certain important story dungeon (Vordakai). See attachment.
Have also noticed some spelling mistakes here and there, which would be nice to get weeded out. But I guess I've acted like everybody else who come upon them. Notice it, but just keep playing, and I don't exactly recall now the precise dialogues with errors. Not terribly helpful :P
