I don't know if this is new with 0.3.3 because I skipped 0.3 and 0.3.2, but the input length for talking is quite short now. I hadn't run into a length limit in 0.2.
I limited it to about 33 words as a lazy way to have guarantees on the maximum possible amounts of tokens left after updating the long term memory of an NPC without having to do multiple API calls asking for tokenization, since I didn't think people would type that much in one message.
I'll find a way to uncap it again for 0.4, which will probably be ready on monday.
