Hi, i've been battling all day with this issue..
I have come to the conclusion that it cannot be the Pallete as I have tried stripping all custom module blueprints from the module and it also occurs when trying to DM the starter module that comes with the latest version of CEP.
I beleive that it is some kind of local bug issue, but it has occured on both of my computers. A full, clean reinstall of NWN and CEP did not have any effect.
When I used to DM the same module I had intermittant DM connectivity.
How do I fix this? Searching online just leads to dozens of instances of the pallete being blamed, and it doesn't seem to be the issue in this case. Something CEP related I imagine..
