I have just woken to find that today's quest is "On the way home"
I have to produce a codex before the end of today.
It is impossible to achieve this as my bookmaker is being upgraded, but even if I was not upgrading, unless I am lucky and he is empty at the start of the day, I cannot see how I can complete this quest without using a significant amount of gems.
This will be the first quest I have missed.
Any other Settlers had this problem or a similar one?
