My Skyrim is heavily modded, over 400 mods, many of them are merged. Its very stable. But some mods that work fine for many cause crashes in my game. Those mods are: Burn Freeze Shock Effects, Realistic Room Rental Enchanced (full version) and Thieves Guilds Requirements. One thing that is common for them - scripts working outdoors, which I think is a real issue. I had same problem with old version of Apocalypse Spell Package and game crashed like crazy. Then I switched to no scripts version and it became smooth as butter.
So my question - is there anything I can do? I really want to use those 3 mods, especially RRRE. Tried to disable few other script heavy mods in case scripts just overflooded engine, but it didnt help.
