@@ -91,6 +91,10 @@ KNOWN BUGS
 [list][*] Start of scenario saves have some known bugs, they can't be loaded correctly and they don't get minimaps in the preview pane. (The preview part of this is by design however, the map is not known for a start of scenario save at the time of the load dialog and it cannot be previewed.)
 [*]Map labels do not work at all in networked multiplayer, see bug [bug]22251[/bug].
 [*]Random map generation causes Out of Sync in mp campaigns. However, a potential fix was pushed to 1.12 today, see bug report for bug [bug]22307[/bug].
-[*]The Legend of Wesmere campaign has multiple lua errors that on some scenarios cause the map to be oddly shifted, and cause you to lose your recall list and gold. Bug [bug]22221[/bug], bug [bug]22073[/bug]. There are some known workarounds, see here: http://forums.wesnoth.org/viewtopic.php?f=51&t=31609&start=15#p572120
