Chunk commit not available during Amend
When in the Commit screen and "Amend current revision" mode, it is not possible to select individual chunks (as you can when in normal "Commit changes" mode).
This means if individual chunks were selected on the original commit, it is not possible to select the same chunks when amending.
Using THG 2.8.1
Not really sure whether this is by design or it is a bug... so will set as enhancement.
