CHANGES.txt file wrote:On several occasions people have noticed that the Forge deck editor and/or quest mode card shop would not open or display. We have also received reports that some of the tabs/panels in the deck editor are missing. There has also been reports that Forge will crash while creating/populating display components during start up or crash when a match is started.
One or both of your layout xml files may be corrupted in some fashion. Try deleting the file(s) named "editor.xml" and/or "match.xml" that are now located in your userDir/preferences/ directory. This should force Forge to then use the default layout xml files instead.
