It is unclear whether if I have IS-7 researched and I own T-10 and IS-7 both, will I get the new tier IX and lose T-10 while its experience moves with it to new branch or I keep T-10 and get the new tank aswell? Also if I lose T-10 does it stay researched or do I have to grind experience to unlock it again?
