This is an old annoying bug which sometimes you may catch at the advanced levels. More heavily modded game, higher the level of the party, greater the probability that the game will crash when you hit the Rest button. Sometimes I can finish the whole game without a single crash, but sometimes it starts right after Spellhold and becomes worse and worse. Some areas are more susceptible to the CTD than others. For example, the Pocket Plane is really sensitive to that.
After few years of experiencing this occasional bug, I have decided to find out what's going on here. After many trials and errors with removing different characters, items, scripts, bringing back other characters, playing different scripts, memorising different spells, removing spells and effects and so on, I found that if you: 1) don't save in the area before the rest, and then 2) completely heal your party before the rest in this area, the crash doesn't happen.
It seems there is a bug in the engine relating to healing the party members of high levels on rest.
Any ideas about that?
In most of the areas where I want that the party could rest, I placed the related character healing the party and allowing it to rest without crash.
