Does the module updater displays any other messages? Abut PnP weapon proficiencies, and 99 bard song uses - the PRC was not installed correctly - merge hak should go on top of all haks (will fix PnP proficiencies) and prc_rest should be added to OnPlayerRest event (fixes bard song uses).
I don't have computer with NWN in front of me, but the updater stops relatively early. When it starts to build a merge tlk, it announces that the custom content (PRC) and the module contain content that can't be merged, and the operation aborts.
The merge is #1 in the hak list, but weapon proficiences are broken anyway. (I agree that in theory that should solve the problem, but it doesn't in this case.)
Before the updater always worked, even in installations where it builds its own merge hak instead of using the official one. However, when the updater does that, I have to install the newest PRC on a fresh copy of EN 4 each time a new version comes out to get the new material to work properly. I assume that has somethsing to do wtih the way the installer creates custom tlks and haks, but it is a real pain. I'd like to just be able to use the official merge hak and tlk, though at this point I would settle for anything, cumbersome or not, that worked.
Thanks as always for your help. And by the way, thanks for getting sublime chord done!
