Ok, I have a really bad bug in my save: All my Spell success rates appear to be lowered from time to time. On a saved game of today I have up to ten per cent lower success rate for every spell than on a game saved yesterday. Of course, all stats and fatigue were full, no red numbers. And this is not the first time this happens. Last time I noticed, I went back to an older save which still had the higher values, but I believe they may have been lowered already. Now it is way too late to go back, I could as well start a new character. Which I don't want to do.

Anyway, when I use http://www.uesp.net/wiki/Morrowind:Spells on my spells, I get much higher numbers than are displayed in my game, more than double for some spells. But on a new char, the formula works. I have absolutely no idea what could be causing that, but I suppose that this should not be due to any mods, as the spell success formula is a basic game mechanic that cannot be modded, am I right? Anyway, I use GCD and many other mods. I could not find anyone with the same problem on the internet, only people whose success rates were all set to 0, and this most of the time happened because of using the god mode. I have never used the god mode on my character, I believe, and I have definitely never saved a game after using god mode. And of course I haven't used it since yesterday.

Everything I have tried so far was in vain: I tried deleting spells from my spellbook, which caused the old (and already wrong) values of yesterday's save to show up until I closed the menu, then everything went back to as it was before. I tried to change my race, class and birthsign via the console, which caused all my spells to disappear, but the ones that remained due to race and birthsign still showed the old values.

So, I post here because maybe someone has an idea which might still help me with this problem. Also, if this is a game bug, could it by any chance be fixed by the MCP?

Thank you in advance!
