Replacing both the GlobalVarsV and AlignmentmanagerV sections (the first two in the data.000 file) with those from my data file before the imp council quest will allow the game to load (either individually would crash trying to load) and fix the problem (Zaknadrix was friendly and I could teleport to the bee/wasp garden and recruit Antx).
Unfortunately the data around the listings for these two imps in the alignment section are the same, and there are no obvious mentions of imps otherwise that are not related to the wastelands. Practically there are too many differences to be able to narrow down the exact problem.
However, if you ignore the imp council member quest for now and complete everything else, then you should be able to just replace those two sections of the file and keep playing without much risk of conflicts. I left the imp until pretty much the end, anyway, to get the best effect from the jug in that world that gives you enough experience to reach the next level.
Oh, and a belated welcome to the forum.
