My teams' Harvester takes out my AT mines, not sure if this was an issue before but I've had it happen a couple of times with the new patch.
EDIT: It seems all friendly vehicles are affected. I just placed some AT mines with a Mendoza on Under, friendly Flamer ran over them with me standing next to the mines. Mines went off and I died!
Been trying to replicate the bug [if it is one] but it does not always occur. No idea how to trigger.
