bug_report_tiny.png 04:56  Bug report #1831 - speech*.pak not found
guest : Issue created
I have the base game installed on Linux Mint through Heroic and can't get past the setup. I direct the installer to the Arx Fatalis folder but I'm told that it can't find the "speech*.pak" even though it's right there in the directory.

From the install.log:
