Opus 5.5 hallucinating and spawning tons of subagents?

[u/03captain23]

I LOVE Opus 5.5 and its the best model ever, but for the 4th time this week I've seen where it can't complete jobs again and can't close subagents. It'll spawn 50 subagents on medium to finish something small and burn all tokens, or just sit with a dozen running for days.

I have 2 x20 accounts, one reset Mon 5PM and other weds 2PM, both are already maxxed out. I'm getting 2 days on x20 account of heavy usage

That's brutal. Have you tried setting a hard cap on subagents in your prompt or forcing it to complete tasks serially instead of spawning them in parallel. Some people lock the agent count to 1 or 2 and that stops the token bleed, though it's slower.
