I also am having this problem outside the townhouse in the medical section when I try to find Bridgette
If you are having problems there then, you are probably using an older version of the gallery mod on a newer version of the game. Remember to check that the version number of the gallery mod matches the version of the game. I am going to assume that you are trying to play the latest version of the game 0.20.2.
1. Download and extract the attached file. It should have two files in it, Map 147 and Map 148.
2. Open the game folder and open the www folder.
3. Open the data folder and add and overwrite the two files from step 1 to the data folder.
4. Once the previous step is done, download and install the latest version of the gallery mod using the link in the OP post.
That should fix the issue. If it doesn't then re download the game install the gallery mod on the new version and carry over your save.
