I didn't want to say this explicitly in my initial answer, but here is one of the main reasons for having removed these scripts from the official 1.8.5 distribution.
Please put it back. Also it looks like there might be a more recent version on the AIP site. Might be worth reaching out.
It just does not work this way. I cannot maintain scripts being developed backwards to PixInsight. When that happens, the scripts in question cannot be part of the official distribution. In other words, if a software product is being developed on PixInsight, but
outside PixInsight, then it has to live independently.
If Alejandro has made these scripts available again from PixInsight Resources, that's fine, but please understand that these scripts are unofficial from now on.
