I've noticed a few bug, glitches, and problems:

-Pinatas crash game when clicked, must pickall to pick them up.

-Colored Tiles (Wired Add-on Tiles in General) Do not let you place items on top of them.

-Public Room Furniture cannot be moved, clicked, or picked up without pickall.

-Timers don't work properly, freeze and banzai timers don't work at all.
(Side note, games don't work well like Freeze, exit tiles don't work etc..)

-In the Teleporter store, Teleport Pad doesn't have a skin and appears as the black box.

-Black USVA shelf doesn't have a skin.

-Diagonal Walk isn't working properly, especially on rollers (snake mazes).

Suggestion:
Can you add BC Blocks of Standing Triangular Angles?
