On Livonia map while standing behind my built fence I get clipped with the barb wire attached to botton of my fence (not tried with upper and lower barb wire, just lower). My fence is positioned correctly.
When my gate is opened and I pass through I get caught on invisible barbed wire which was previously in the closed gate position now open it should not have an effect but with the gate open the barb wire still effects the OPEN entrance area.

To counter this and avoid damaging my clothes I have to jump after opening my gate.
