When loading a build that has a Sakura, it loads the correct amount of stacks, but the each stack is implemented as the wave 1(?) version (70 hp/5% as)
Replicatable by building a Sakura on wave 11, letting it survive 3 times, then save and reload the build and Sakura loses stats. Goes from 1940hp/39% AS to 1580hp/13%AS.
