I believe it is a bug with Turambar's mod. I would love a drop-in fix, but I am not willing to reinstall.
Apparently, the new version of tobex allows me to use opcode 232 for the spell wich now apparently causes the problem with opcode 272.
I've been testing it for a while, and it appears to work and to allow saves (I've added an effect with opcode 8 and have been going around with shining pink and green wolves in my party for some time).
I will fix my code now, and hopefully a new version of my mod will come out in the next days.
Unfortunately, Bill Gates messed up the most recent version of my installer, so I won't be able to release some other new things I had already prepared immediately. But I will, at least, try to fix this particular problem.
I think that putting the TUDRWUD spell from the new version of the mod into your override folder should
edit: I've uploaded the new version; I hope it works (as it did in the tests).
