Thanks for the update. I have a lot of "pairs" of objects, where they are initially single objects, then they magically merge into a plural object when they're together. I think I'll revise my puzzles so that the two single objects initially appear as plural objects and there's no need for disambiguation and no need for the merging (although this part was working really well). It will make those puzzles a bit easier and will make my code a lot simpler. Pity, as I'd already done all the work on that.
Incidentally, I just confirmed that you forgot to update the version number on the latest update. It should have been Beta 23.
