Bunker in IA invokes a basic looking MK1

[Zumbies]

Hello....I upgraded my bunker recently in IA which should invoke a MK10, instead, a basic MK1 gets out...I don’t know if it’s only a graphic bug or if it’s stats are also those of a MK1...can you check this? Not fun to make efforts to upgrade our buildings to have this kind of outcome. Thanks.
