Oh no, we haven't run into that one ourselves yet. Could you let us know a bit more about the error (either here or at support@boyslaughplus.moe). Thanks for letting us know about this! We'll see what we can do to fix the error
Every once in a while when I attempt to start the first chat with the others (Suuj and Ex etc) it'll just say 'we can't load this'. I did try closing and reopening the window and that worked, but I found it pretty weird as well.
