So if you are to stack bundles inside of each other repeatedly, then after the size amount on the bundle is maxed out, put the bundle in a chest and Ctrl+Middle Click the chest, now put that chest in a bundle and repeat the bundle inception process. After a certain amount of iterations, your Player Data will be corrupted and reset, which kicks you from the server but upon rejoining all your played data is deleted making you lose all items and saved data you may have had. 

Furthermore, if you stop just before your player data gets corrupted and put the bundle in a chest and then unload the chunks when returning to the chunk, it will have been reset to its default generation. 

If you save this overfilled bundle into your hotbar, then save the hotbar. When you try to reload that hotbar. All pre-saved hotbars will be deleted.
