Yeah, I am unfortunately reporting back with another broken tank, number 4. This time it lasted 1 1/2 heats, because I dremelled the tank holes an oval shape to give the posts more room to flex. I am convinced the material used in the tank is the wrong choice.

Hoping Tekno give us a v2 tank soon or another solution, at this stage I am no longer able to run the buggy, even though I really want to. Disappointing.
