So like an hour before reporting this I went into my shulker box filled with dusts and grabbed some from the shelter box. When I went to go pick it up with my pick which had detonate on it the shulker box fell but without any of the items that were still stored in the box.
Detonate is known to cause issues with shulker boxes. Please do not mine shulker boxes with detonate for the time being until this is fixed. The thread will be closed but we will notify you when the glitch is fixed. Thank you!
Thread will be open for 24 more hours in case you want to reply.
Thank you xerge
