WAR client patch 1.0.2 is live. You can read the patch notes.
You can also discuss this with other developers on thewarwiki ... I've already uploaded a ZIP file with all the changed interface.myp files in their 1.0.2 versions, linked from the wiki. It was created with easymyp 1.2 and kdiff3 for Windows.
Note to users: uninstall all your addons, then install them in bunches of 5 or 10. When you find a bunch that breaks your client (crash to desktop), uninstall that bunch and install them individually. When you find the culprit addon, report the bug on the bug ticket tracker of the addon's project.
Note to developers: immediately test all your addons. Look to the changed interface.myp files for clues on how to update them to be compatible with 1.0.2.
