The forums are intended to be used to discuss issues with the various codexes, not for reporting bugs. If you think you have found a bug, please perform the following steps:
(1) Make sure you have the latest file release installed, and that the bug exists in that version. Details can be found here: Current release details
(2) Go to the Bug Tracker (link is on every page in the menu at the upper right), click on the name of the codex that the bug applies to, and check the list of existing bugs to see if it has already been reported.
(3) If the bug is not already listed, post a new bug report by pressing the New Issue button. Please include details on how to reproduce the bug - in some cases the bug will show up if things are done in a particular order, and without having those details may be difficult to track down and fix.
Don't post duplicate bug reports! If a "bug" is marked Invalid, this normally means it is not a bug - check the comments attached to the bug.
