No, Alec, the problem remains. As before, I am able to create a new custom block which then shows up along with the previous, successfully created block in /plugin/generic/CustomBlockManagerPlugin/settings. However, only the new plugin appears in /plugins/blocks. Again, the first one returns to /plugins/blocks and functions as expected when the newly created one is deleted.
I can ask for a specific file(s) for you to see if that would help (and you tell me which file(s))?
