Hello, I also use this tool in Debian 13. I'm creating my RPG with this tool. (version 1.1.1)
I also encountered the same issue. "Export" button doesn't work fine. (It does nothing... No reaction...) And, debug log is also nothing special for this issue. So, I would like you to fix this issue.
And, if this tool requires additional libraries or environmental settings, please let me know. Thanks in advance.
