Bug Fix and Manual

Update 1.227.433 has been released very early as user reports came in. The new loading method was incredibly slow, and so has been reverted back to the old loading method for now.

We now have an online manual started, it has been added to the help menu: https://docs.google.com/document/d/1yhvyJXfK06S6v6HBG13h2kkPqOagU6fEaGZlS-drsTk/... (it is very early on)
