New gate bug started today

When I build walls, I'll task 1-2 villagers to build a longer walls usually in 2-3 segments by holding down shift and dragging out each segment.

Then I'll place a gate in one of the walls to allow units to move - still holding shift.

In 4 games now I've gone back to check on those walls and I'll find the villagers I tasked standing at the gate doing nothing. Selecting them and right clicking on the gate would normally have them build, but starting today the gate is unclickable.

If I delete the gate foundation and replace it, they go right to work and then finish the walls as normal.

If I can get a couple people to replicate this, I'll submit a bug report clip.

Thanks
