I just looked it up in the manual. I am using OPTIONAL_EXTENDED_VERBSET, but I didn't realise there was a separate OPTIONAL_EXTENDED_METAVERBS. It probably doesn't matter for a production game, but it may be useful during testing. If you're using an interpreter like Windows Frotz, it captures a transcript anyway. Does your interpreter have a similar feature?
I can't do an update now, as uploads are banned during the jam period. Sorry about that.
