I think one of the metarooms might have put an additional rubber ball catalogue (rubber_ball-fr.catalogue) in my Docking Station catalogue folder. After injection of the Children of Capillata the engine started to throw a lot of catalogue errors my way.
Catalogue Error: CLE0019: Two tags with the same name "Agent Help 2 21 31" but different contents at item 1
