Let's begin by reordering the block trees executions. Block trees 35 and 37 need to be the last ones to be executed, so please change number in all other 'No position' and 'if position' blocks to be lowers than 35. Additionally they should be ordered from lower to higher. This means the 'no position' one should be the lowers and the 'if position' for the highest lot size should be the highest but still below 35.
