While using south facing dead coral tnt duplicator with west side frame(pic as attachment) Tnt drops straight down with no horizontal movement. Earlier versions 19w42a and 19w44a model of the tnt and and hit box of the tnt both fell down the same route straight down from the point of duplication. On version 19w46a/b the tnt hibox still follows this route according to my testing but the model is shown in the next block over to west. This can be proven by placing obsidian ring some blocks under the duplication point so the tnt has straight line thru the ring, Tnt will fall thru the ring even tho the model hits and goes thru obsidian block.
