Unable to open chests close to walls (right or bottom)

[lgrossi]

Whenever you're nearby a wall (right or bottom sides) that has a higher level tile border the visibility of your current ground gets weird. After that, you become unable to move items in this sqm or even open chests.

Steps to reproduce (include any configuration/script required to reproduce)

1. In a ground+ level go to a wall in the right side that contains a higher level border tile over it.
2. Try to drop items or open chests in this specific sqm.

Expected behaviour

You should be able to normally throw items or open chests in sqms under this situation.

Actual behaviour

You can't throw items or open chests in sqms under this situation.
