TobEx silently already fixed some of the wrap around issues (Strength Mod, Dexterity Mod, Save vs. X Mod), but I've added the rest of them, I hope.

Fixes a G3 reported unfixable exploit.

Attribute Drains Can Cause Scores to 'Wrap Around' To Max Values

This is another fairly well-known exploit, typically abused with the Rod of Terror and the Ring of Human Influence. The Rod of Terror will occasionally drain charisma from its wielder, eventually taking charisma to zero and killing the character. However, while wearing the Ring of Human Influence, the actual charisma will continue to decline to zero but will not kill the character as the ring keeps their working charisma at 18. If the Rod drains more charisma, the actual score will 'wrap around' from 0 to 25. The Ring can then be removed, leaving the character with an artificially inflated, god-like charisma score. This is hardcoded and can not be fixed.

Also should fix the lore wrapping issue and thieving skill wrapping issues reported in the Wish List.

Aaaah. Great. For increases too?

[Ascension64]

Should do.

Am i missing disarm traps or hideinshadows/movesilently anywhere (vs stealth, that i know it's a combination of both).

[Ascension64]

HideInShadows, DetectIllusions, and SetTraps shouldn't have the problem, since they don't allow setting of INSTANT_PERMANENT changes. It is possible to make them wrap using timing mode 9, but that is absolutely permanent and I can't see a use for that - unless someone wants to make a kit where one of these skills gets worse with higher level...
