Hi there. I have been GM-ing this adventure for my little group of stalwarts and we have been enjoying it. I have, however, noticed a small problem with the maps of the Research Facility in this module. There are quite a few doors missing. This leads to areas being inaccessible to the players. I have noticed this error because I also have the hard copy of the adventures; bought before covid-19 drove us online! Without these I might have found the missing doors a bit of a puzzle. Something to put right, when you have the time, for all those who follow after us.
