Formed qing and lost my cores

[jamie067]

I've been playing a game as Haixi, then Manchu, but when I took the decision to form Qing I lost 8 of my cores. Is this supposed to happen?

It's a feature.

Working as intended, git gud scrub.

Reported at least 20 times. I think someone also reported that this happens if you got any free cores from the form Manchu decision, you lost them when you form Qing.
