After saving game with this mod then remove this mod and load the save game, the game did crash and I realized this mod actually didn't delete sky objects properly.
I didn't realized loading invalid models from save games crashes the game until then, though. So I uploaded a fixed version.
All I had to do to resolve this problem, was add this trickfunction makeObjectUnsaveable(obj) local objPtr = getObjectPointer(obj) objPtr += 0x13C memory.write(objPtr, 6, 1) endThis makes objects persistent but unsaveable.
Cool, I'll check it out when I get back home. Thanks!
