Have a weird issue going on. Before I upgraded, I completely uninstalled several add-ons that I knew had been rewritten for 1.2. After doing so, I upgraded to 1.2, and then installed the new versions. With one of the add-ons, i'm getting this weird problem of a template belonging to the previous install showing up as being outdated (the yellow warning on the main ACP screen). When I select merge, this is what the system tells me:
No previous version of the parent could be found. Merging is not possible.
