Thank you for letting us know about this! Your investigation did properly identify the source of the problem: Because Deka doesn’t speak verbally, no character was defined ‘d’ for just ‘deka’, and instead there are two; ‘dw’ for ‘deka writing’ and ‘dt’ for ‘deka typewriter’. So, when we went to track the character in the romance/friend list, it was too easy to pick the wrong one.
Thanks to your comment, the issue is fixed internally as of today! It didn’t make it into the most recent Patreon build (from last Friday, 10/27), but will be in the public release of Elsie’s chapter 2 content- which should be coming out around the end of November.
