A command to build houses randomly disappears out of shit-queue

When playing Malians, you wanna place your houses around 1st pitmine very early.
When doing this, the “build house” command gets kicked out of shift-queue again and again.
You have to press q+q again.

I feel it has to do with the villagers that drop off wood to tc.
When the wood ressources in the bank changes, the command gets cancelled.

So what happens in detail:
You select a villager to build houses around the pitmine and start placing some, the villager starts building.
As more wood (50+) ##### ### ### wanna place more houses.
You hold shift and press QQ to place a house and left-click on the location.
By the time the 1st blueprint is placed, your shift-queue is ended/cancelled even though you are still holding shift.
So you have to release shift again, hold it again and press QQ again to build more houses.
But it happens again…

Please have a look into it, as it happens pretty much every game and disturbs the build flow.
