Thanks for reporting the bug, I'll have to remove the mod until I figure it out. I've tested every version and only managed to replicate it with the mozarab one, which incidentially is also the only one that adds the aljamí culture and the Banu Ishaq dynasty. If it still happened to you with the other versions it might be because you used the same save, which will most likely already be corrupted, or unpacked one version on top of another which will overwrite some and mix other files.
On the other hand, I've also noticed that HIP seems to have changed the name of the moravian culture to slovieni, causing a splotch of no_culture under bohemia when you use my mod. Thankfully it's an easy fix, I might rectify it later if I have the time.
