 ### To Be Fixed

 ### Fixed
 
-1. Entering an invalid regex (e.g., unbalanced parentheses) in the [find/replace form](/docs/README.md#findreplace-form) no longer causes plugin crash and instead simply causes a message box to pop up and an early return.
+1. Entering an invalid regex (e.g., unbalanced parentheses) in the [find/replace form](/docs/README.md#findreplace-form) no longer causes plugin crash and instead simply causes a message box to pop up and an early return. However, the find/replace form's tree view is lost as a result, and so the find/replace form will need to be closed and reopened afterwards.
 2. `Next chunk` and `First chunk` plugin commands (and associated buttons on chunk form) now add a new chunk if you were already on the last chunk (for `Next chunk`) or no chunks had been added.
 3. Reduced flickering when moving between find results in the find/replace form.
 4. Fixed bug where chunking a JSON file and then chunking another JSON file would cause the second file to be chunked incorrectly.
