What's Wrong?

Sometimes using the teleport command when moving to the cli works like a charm. other times i get

API Error: 400 due to tool use concurrency issues. Run /rewind to recover the conversation.

after I prompt once the conversation was restored. using /rewind is useless because the old parts of the conversation have a triangle warning symbol with no way to go back to part of the conversation. so nothing can proceed once this error happens

What Should Happen?

We should be able to continue on with the conversation in the cli
