Unit Killed Due To An Upgrade

[jakarecosta]

I'm Having a Problem i got a dinamic recipe sistem that saves what material you made the item from
now i'm trying to make the bonuses of the material go with the created item
the problem is i'm using upgrades to do so but after i'm done with the first item the second i buy another material it kills my hero

i dunno if this happens with another tipe of bonuses haven't tested yet

When I used to work with Wc3, it was impossible to reduce research levels. I don't know if that has been changed with one of the newer patches, but I'd be surprised.
