Problem with the placement of chests resulting in a failure to connect properly with the adjacent chest.
To reproduce:
Place line of single chests in creative mode. While rapidly rotating your character's head (use higher sensitivity if necessary) and while aiming at a chest, press both LMB & RMB at the same time to instantly break and replace the chest. This should create a visual glitch with the chest incorrectly attaching to other chest (see picture) This will fix itself when block is updated or after relogging (see other picture).
Expected result:
Chest will stay in single form as shown after it has been updated or after relogging.
Observed result:
Abnormal connection to adjacent chest.
