Heavy MG hidden from hangars during event?

Was tinkering with a custom hangar and couldn’t get a HMG to appear in squad menu. Downloaded some other hangars from Enlisted Sandbox and they don’t have HMG as well. Launched game with default hangar - no HMG there as well! Am I right to assume Chinese New Year event is to blame for this?

Anyone else with custom hangar who can’t see HMGs in squad menu?
Is this intended change? How can I get a HMG to appear?
