Seems like one of my extensions is suddenly too demanding for Inform since the update. But if I try ‘Use MAX_PROP_TABLE_SIZE of 50000.’ as suggested in the error message, it still claims that it is set to 30000 like before… Help? 
Ok, crisis averted. I rediscovered console panel. MAX_EXPRESSION_NODES was to blame. Is there any reference where what these settings are used for?
The Inform 6 compiler has some built-in documentation. See this file:
Much appreciated!
