There is a bug in PyScrabble in which more than one word can be played at a time if both words are in a line (horizontal or vertical) and both words join onto existing words.
Example - view the saved game "unjoined word bug" on the UK public server
First word played is WARN
Second word played is both RIDE and ONE separated by a space and resulting in a Bingo score.
This will need to be fixed.
For some reason that example saved game got deleted.
I created another bug example game and saved it. Same conditions, different words used.
That was me who deleted it :)
Thanks for pointing it out. I'm aware of how to reproduce it and have fixed it for the next release.
aha! I thought I had done something to lose it by mistake :)
