What's Wrong?

Sometimes when queuing the message, claude code will swallow it (ie: removes it from the UI, but not send it either).

This happen more often when claude is finished a task, but still Combobulating...

The message is still in the history (if i hit up arrow), but its not send to the context.

What Should Happen?

Message should not be swallowed
