When I run maintenance from the console I get some errors like
Brick ‘xy’ not found. Please check table object_brick_query_xy_1
Similar errors for all my bricks and fieldcollections. I think it has to do with case sensitivity. My items are named camel case and maintenance task is searching for lower case named definition files, because it fetches their name from the lower case table names.
Application works fine, but error message is not nice.
