close this bug report. it is fixed! sorry...
so get a bundle in creative inventory, on switch and put a bunch of items in it. the take out and delete hotbar buttons are the same button, so if the bundle is not in my hotbar, it deletes my hotbar when i try to take something out. and if the bundle is in my hotbar it deletes the bundle then displays full and empty textures over each-other. this is not that bad but still very annoying.
this got fixed in main version, please close this bug report. sorry!
