What happened?

After roo attempts completion, subsequent follow-up messages always show this:
Response interrupted by a tool use result. Only one tool may be used at a time and should be placed at the end of the message.

There is no effect on the usability of Roo as a result. This is not a major issue, but perhaps a sign of inefficiency somewhere?

The user is using Memory Bank but that has no effect on this problem. Other users report getting this same message and are not using Memory Bank.

Additional context from the user:

the problem is regarding OpenRouter Sonnet 3.7.
if i use openrouter sonnet 3.5, it doesn't occur.

for what it's worth, i've downgraded to sonnet 3.5.
my experience with claude 3.7 so far has been that it's worse than claude 3.5 for existing repos. it's:

• too chatty, causing it to duplicate lines of code. claude 3.5 had the opposite problem, where it just said // rest of the code remains the same but you could prompt away from this
• commits to its mistakes. claude 3.5 was very non-committal, always agreeing with whatever you said. claude 3.7 commits to wrong things. this compounds and ultimately delivers wrong outcomes.

maybe a bug / server error on anthropic's side?

Happening to me even in Claude Desktop sometimes after tool use. See screenshot.
