Hi guys, im having a huge problem with quester. An 'internal error' ensures that i my quests created, edited and deleted yesterday have not been safed. On monday, when i started to experiment with quester commands, it worked fine and the 'test' quests still exist, even though i deleted them yesterday. All my work of around ~ 4 hours is gone now. i was hoping to set up my server until the weekend.
i really would appreciate your help.

i havent changed anything on the server, neither from mon to tusday, nor from tues to wednesday. i dont know which information you need to help me, but this is what the log says:

*hope my english is ok for ya :b

Quest names in 0.6 can't contain dots, It is mentioned in red under known issues here: http://dev.bukkit.org/bukkit-plugins/quester/pages/documentation/#w-known-issues-todo.
It is fixed in 0.7 dev version and I will not be fixing it in 0.6.
