Hello, so i have noticed that for spawners, you can stack them, but it is buggy, not sure if i should move this to the bug section. But for spawners that have levels can not be stacked, some spawners that you haven't placed down can be stacked, but once mined can not be stacked because it has a level shown, and sometimes when you do have stacked spawners, it is buggy, what I mean by that is once you stack them, it gets un-stacked and drops form your inv, or pv/ or echest once you exit out of the echest/pv or inventory, and drops on the ground. After that happens you go back and it is able to stack, so it is probably a bug. But for the level spawners that are like level5 for creepers or other spawners that can be upgraded, I would really love to see them stack-able in the future, And as well, i'm mostly creating this because it wastes space in your pv because having 30 cow spawners not being able to stack wastes inventory space in your echest or pv and eehsts. ty for reading. I'll put a video of what i'm talking about when i get home from school.
