Why is the BF-110 Undercarriage collapse on taxi

[KoN_]

Yesterday while taxing too the runway my undercarriage collapsed or some invisible force made my bf-110 tip over onto its nose it was very strange hard to describe .

Also the other night watching a BF-110 taxing towards the runway , the right hand-side undercarriage collapsed without any reason  .

Never seen this.

Been doing a vast amount of missions in PWCG as a 110 driver and I always taxi off the runway after touch down when the mission is ending.

Maybe inadvertently the gear up switch was activated?

To fast rolling in the dirt?
