The vanilla tables fine for me and I don't see any problems with the schemas. If you can't open the vanilla tables, something was probably incorrectly changed in your PFM files (or you're using out-of-date schemas) and I would recommend getting a re-downloading the newest schemas. If you can open the vanilla tables either the mod is uses an old table schema that I accidentally broke or the modder did something weird to the table. I can check both of the latter possibilities if you provide a copy of the mod or its source. I might also be able to provide additional information if you tell me which table schema the mod is using. The table schema version number can be obtained by opening the mod, right-clicking on the table, selecting Open->"Open DecodeTool...", and in the bottom-right there will be a line that says the table name, Version #, parsed with #. The Version # is the schema version the table claims to be using. Warhammer 2 is currently using version 19 in vanilla.
