The Enhanced Slave List should work with v1.0a. However, I've done only very minimal testing.
The pregnancy mod I uploaded a version compatible with 1.0a.
Not looked into the others yet. The UI is unlikely to be compatible at this time.
Tested nav bar, mansion UI and better info panel, they do work with 1.0a, but are not compatible with slave list :)
As a side note, they were complaining about some hide function in mansion script.

Since the NavInfo files are installed by full file replacement, there is a decent chance they will mostly run. But it also means that all the files it touches are being reverted back to Strive v0.5.25 status. Any changes/improvements that were made to make the game v1.0a release are being destroyed in the files the mod uses. There could be additional complications, but the loss of fixes is enough to make it not really compatible. Hopefully I'll get some time upgrade the mod to 1.0+ ready soon.
As for slave list error, thanks for the error report. I really should look into the v1.0 code and see where changes were made. Might be the slave list isn't as compatible with the update as I'd hoped.
