Interactables spawning on very edge of "island" stages and launching items into the abyss.

[Aaron00000]

More than once I've had chests/cradles/printers/etc. spawn at an almost 90 degree angle on the slopes around the perimeter of the island-type stages and lobbing their contents into the water. And if I use a mod such as Wolfo Gameplay Tweaks or ZetTweaks to teleport fallen items, the item falls off, respawns back on the slope, gets carried by the momentum of the fall and slips back off the slope, and then completely freezes the game (and the log isn't any help, as the last line is merely "[Info : Unity Log] tp item back".) Is there any possibility of adding a check to prevent interactables from spawning so close to the edge of said stages?
