1.7.54 Plan mode LLM cant update plan

Describe the Bug

At about 18% context on sonnet-4.5 thinking max, and it keeps trying to update the plan for a few seconds, then stops, no messages. I ask why it tries again. And just stops. Told it to not use any of the plan tools and isntead just update a .md file and it’s working on its merry way, so something busted in the plan tools.

Steps to Reproduce

Dunno – work with a plan for awhile.

Does this stop you from using Cursor

No - Cursor works, but with this issue

also the plan files created in plan mode are in a hidden location, so it appears you cannot edit or save them. Nor reference them from other tabs, which is not great;
