Long hero sight problem

[Max]

when I meke 2 maps (or more) with a hero, and I want the same hero from 1st map to be loaded in 2nd I use game cache.
In 1st map everything is normal - I place the hero in the map, and play, level, when the map ends the hero is stored as a unit in game cache.
Then i play 2nd map which begins with loading hero from 1st map.

And then there is a problem. Everything goes as normal (loaded hero has all items, skills, levels I gained in 1st map) just one thing. At night he can see as far as in a day (i mean revealing area), which is very long (1800radius) - and he should only see 800 radius.

I've tried everything, and the problem only appears when any hero is loaded from game cache. And this is also in original TFT and ROC Campaign !!!! I've tried to change that in object editor but the value is ignored when loading from game cache.
Reinstalling game doesn't help - but if it is a game bug, the why isn't it fixed in newest patches???

oO lol nice bug^^ can't you limit sight radius throught triggers?? if not, its engine fault, go report to blizzard! can't help you much

i would be lucky if I could repair it by triggers at least, but there's no such trigger.
