Since patch 2, the schema file has changed making all old mods useless for the patched game. You'll have to use this new schema file to open the database post patch 2. Also, if you want to continue your mods you'll have to port over all edits made to the new database from patch 2. Just put it in your RDE folder and all should be fine from there. DOWNLOAD Now part of RDE download. FYI, the difference is that there is a new table now called tier_difficulties.
